American Slang Explained: 53 Common Words You’ll Hear in the USA

What’s up, bruh? Hang tight: this new article about American slang is gonna be lit! 

If you don’t understand what I just said, don’t worry, there are even some Americans who don’t get them! (For the record, it means: “Hello, how are you? Just wait: this new article about American slang is going to be great!”). American slang is a funny and sometimes complicated thing, and it can be very amusing and useful to learn. 

Let’s take a look at 53 of the most common slang words you’ll hear in America today.

What Is Slang?

Slang is something that is present in any language. It can be described as words and expressions that have been changed or invented in order to express something in a new and unique way. Slang is often used by younger people first (which is why you might hear some older Americans complaining about not being able to understand their kids or grandkids…), but then it spreads even to earlier generations as well as later ones. 

Slang is a way of speaking that brings a community together. There can be slang words used in just one area, like a city or a state, or the words can be used and understood by people in an entire country. Usually, people who are not from the United States, for instance, would not understand the slang words used there, just like Americans would not understand slang words used in Italy by Italians. It is almost like a secret code, in a way, or even a dialect that is shared between a specific group of people that encourages connection between those people.

Takeaway: Slang is a collection of invented or creatively used words that is unique to a group of people. 

Why Should I Learn American Slang?

If you are not American, why learn American slang? It is enough to just learn English in general, right? Well, it all depends on what your goals are. Here are some reasons you might want to learn American slang while you are learning English.

To Understand Movies and TV Shows

American shows and movies are very popular, not just in the United States, but around the world. If you are watching American videos in English on streaming platforms, you are sure to come across some American slang. HBO’s The Wire series, for instance, is very well-liked, but also very hard to understand if you don’t understand any American slang, since the characters use it a lot. If you would like to practice watching shows with American slang, Jolii.ai can generate subtitles and even create lessons based on them to make that new knowledge stick.

To Sound Like a Native Speaker

Learning standard English on its own is enough for you to get by in the United States and be understood, but if you only speak perfect English all the time, you risk sounding a bit stiff or overly formal. Learning some American slang can help you fit in in the United States and to sound more natural when speaking with native English speakers.

Curiosity

From a language-learning standpoint, slang is just interesting. Some words are just completely made up to express an idea in a different way than previous generations did and others are used in ways you wouldn’t expect. Take the phrase “let him cook,” for instance. This relatively new slang phrase means “let him work,” or “let him talk/explain.” In this context, it doesn’t literally mean, “allow that person to cook a meal.” But why is that? No one really knows. Being curious about learning slang for fun or for academic purposes is as good a reason as any to learn it!

Takeaway: There are many reasons to learn American slang, like being able to understand American media, to sound more natural when speaking English with Americans, and just simple curiosity.

FAQs

Is it rude to use American slang?

Some American slang can be considered rude, but much of it (like “cap” or “lit”) is just a different way of expressing a thought. However, everything depends on the context: if you are speaking to someone in a formal setting, leave out the slang. 

Do Americans use different slang than British speakers?

Slang varies from country to country, and even sometimes from town to town. So, understandably, all English-speaking countries have different forms of English slang, making it hard at times for Americans to understand British people or vice versa. British slang words are considerably different from American ones. Being able to distinguish between American and British accents is useful especially when traveling or working in the respective country.
