What are English slang words?

According to Oxford, “slang” is “a type of language consisting of words and phrases that are regarded as very informal, are more common in speech than writing, and are typically restricted to a particular context or group of people”. For example, the slang words and phrases we are going to talk about today are defining for two generations known as “millennials” and “gen z” – but mostly “gen z” because – let’s face it – today’s teenagers have come up with tons of new slang terms that even I, as a millennial, have trouble understanding. Praised be the mighty internet for slang dictionaries!

Why is it important to learn English slang words?

It may be indecent, colorful, or obscene, but slang is a crucial part of any language. Just think about how criminals started using slang so police or other people who are not in their crime circle would not understand what they are saying. Isn’t that great evidence of how creative people can be? Regardless of their social status or intentions.

But besides being understood only within a particular group, slang can also be general. For instance, almost every native English speaker knows that to be “filthy rich” doesn’t mean to be dirty, but to have a lot of money. In this situation, as Eric Partridge observes, slang changes its objective of being limited to a certain group to easing social intercourse and to reducing the solemnity, pomposity, and excessive seriousness of a conversation.

Thus, it’s important to know English slang words because they bring us closer and while also enriching the language.

History of English slang words

Whether you millennial desperately trying to stay cool – like me –, a Gen X-er striving to understand the new generations, or a baby boomer who wants to be the GOAT (Greatest Of All Time) grandpa or grandma, you’ve come to the right place. Why? ‘Cause we’re about to absolutely slay this list of popular slang words! But first, let’s talk briefly about the history behind English slang terms. This will help you figure out their importance and why all new generations have them.

How has slang evolved over time?

The use of slang has transformed significantly throughout history. Its origins can be traced back to the early 16th century, when it was used as a specialized vocabulary employed by various groups, including criminals, sailors, and beggars.

Then, slang gradually expanded its reach and became more widespread across different social classes and demographics. For example, in the 19th century, the working class embraced slang as a way to differentiate themselves from the upper class.

In the 20th century, slang went mainstream through media and pop culture. Social media and the internet have further amplified its influence, resulting in a rapid evolution that incorporates words and phrases from various languages and cultures.

Currently, slang remains an integral part of our daily language, used to express humor, irony, and social identity. Although some slang words become obsolete quickly, others become part of the lexicon and can stay lit for generations.

Examples of historical slang words and their meanings

  1. Bee’s knees – the height of excellence or perfection;
  2. Cat’s meow – something or someone highly admirable or excellent;
  3. Flapper – a young woman who was fashionable in the 1920s, known for wearing short skirts, bobbed hair and dancing the Charleston;
  4. G-man – a federal government agent, particularly an agent of the Federal Bureau of Investigation (FBI) during the 1930s and 1940s;
  5. Hooch – slang for alcohol, particularly illicitly produced alcohol during Prohibition in the United States;
  6. Jazzed – excited, enthusiastic, or energized;
  7. Jive – a type of jazz music and dance style or slang for dishonest or misleading talk;
  8. Ragtime – a style of music characterized by syncopated rhythms and upbeat tempos that became popular in the late 19th and early 20th centuries;
  9. Speakeasy – an illegal establishment that served alcohol during Prohibition;
  10. Sockdollager – a decisive blow or action, often used in reference to a fight or argument.

But enough history. Let’s travel to the present. Does Gen Z slang sometimes look like some secret unbreakable code to you? Well, you are not alone. But TBH (To Be Honest), once you get the hang of it and realize how relatable and fun it is, it becomes quite addictive to use in daily conversations.

So get ready to hear new meanings for words you thought you knew and prepare for heavy eye-rolling every time you’ll use your newly acquired lingo around teens. Here are some of the most common slang words used in the English language today:


When something is very good, enjoyable, or exciting, you can say it’s “lit”.

Dude, the party last night was lit! Where were you?


When someone is “extra”, it means they are unnecessarily dramatic, excessive, over the top or a “drama queen”.

She invited the entire school to her birthday. She’s so extra!


You can say someone is salty when they get upset or angry over something minor.

Nick is so salty since his parents took away his car!

To ghost someone

When you cut off communication with someone you’re no longer interested in.

OMG! Did you hear Cristina ghosted Matt?

To flex

Another way of saying someone is showing off.

Nowadays, teens have started using the slang phrase “weird flex but OK” as a snarky and mocking response to someone bragging about something considered questionable, bizarre or unusual.

– Andrew’s trying to flex with that new no-name smartphone of his.

– Yeah. Like weird flex but OK.


Lowkey & highkey

Lowkey is the opposite of highkey and it can be used as a way of saying that you liked or done something secretly, modestly or quietly.

I lowkey rooted for Daenerys to remain on the iron throne.

Paul is highkey trying to learn Spanish for Elena.


When someone is shook it means they are shocked or incredibly surprised.

– Did you see?‌ The new season of Lucifer just landed on Netflix!

– OMG‌ I’m shook! I need to watch it ASAP!


When someone is “spilling the tea”, it means they are gossiping.

What happened at Jessica’s birthday party? Come on, spill the tea!

A cold way of dismissing someone.

– You were rude. I’m gonna leave now.

– Bye, Felicia!


Used to express something that is relatable.

– Ugh! I wish I was in Bora Bora right now.

– Mood!


When you are so hungry that you are angry! (probably the most relatable slang word Gen Z taught us).

Not Gonna Lie. Another way of saying “to tell you the truth”.

NGL, I’m not in the mood to go out tonight.


To do something very well. To impress someone very much or to be very good or impressive.

Pedro Pascal’s performance in The Last of Us slayed.

Proof or evidence of something that happened.

– How do you know Jamie is cheating on Sylvie?

– Honey, I got all the receipts.

OK Boomer

The catchphrase and internet meme commonly used by Millennials and Gen Z aims to reject or ridicule attitudes typically associated with baby boomers – individuals born in the two decades after World War II.

– Boomer: Kids nowadays never go out. Back in my day we played outside the entire day.
– Non-boomer: OK boomer.


It refers to someone who is aware of and actively attentive to important societal facts and issues (especially issues of racial and social justice).

Bro, we have a moral obligation to stay woke. Inform yourself!


This is used when someone is bold and doesn’t care about consequences.

– Gaby is gonna report the teacher to the principal.

Regional variations in English slang

English slang, like languages in general, can’t be entirely homogenous. With native speakers dispersed across the globe, slang evolves differently depending on factors such as culture, dialect, and more. That’s why Aussie slang is so different from British slang and British slang is so different than American slang. Different cultures make different slang, just like different countries make different languages.

Differences in words and phrases across English-speaking countries

I read this joke online a while ago: “I can speak five languages: American English, British English, Canadian English, Australian English and New Zealand English”. Every time I remember it, I can’t help but giggle. Stretching over such long distances, the English spoken in these countries can truly be very different. Here’s how:

  • Vocabulary: These countries often use different words to describe the same thing. For example, in the UK, people call “chips” what Americans call “fries” and “crisps” what Americans call “chips”. It’s overwhelming!
  • Spelling: Spelling can also differ between countries. For instance, Americans spell “color” without a ‘u’, while in the UK, they use the spelling “colour”.
  • Pronunciation: Don’t get me started. The differences between British English and American English are plentiful in this sector.
  • Culture: For example, Australian slang is heavily influenced by surfing and beach culture, while American slang has been influenced by hip-hop and African American Vernacular English.

How to use slang words in conversation

Using slang words in conversation can add flavor and personality to your language. However, it’s crucial to consider the context and audience before incorporating slang into your language. Here are some tips for using slang terms effectively in conversation:

  1. Know your audience: Make sure your slang words are appropriate for the person or people you’re talking to. Avoid using offensive or inappropriate slang words, especially around people you don’t know well or in formal settings.
  2. Use context clues: Do the slang words you’re using fit well in the context? If you’re uncertain about the appropriateness of a slang term, it’s best to use a more neutral term instead of taking the risk.
  3. Don’t flex too much: Using too much slang can make you sound unprofessional or immature. Use slang words sparingly, and ensure they add to the conversation rather than distract.
  4. Practice makes perfect: Slang terms are dope, but incorporating them into your vocabulary can take some practice. Start using slang words with people you feel comfortable around, and only then gradually include them in conversations with new people.
  5. Be yourself: If using slang terms doesn’t feel natural, maybe they are not for you. Everyone loves a cool mom or dad, but overdoing it can be cringe. Or at least that’s what teenagers believe.

Remember, slang words are meant to be fun and expressive, but using them appropriately and in the right context is very important.
