For international students, learning a new language like English can be tricky, especially American slang. You may hear dozens of slang terms around your college campus. You might even hear some slang expressions at your internship or job. Our guide to American college slang words in 2021 will help you better understand American slang and to how to use it.

What Is Slang?

Slang terms are words or phrases that have a cultural definition that is different from the literal definition. For example, when you “keep your cool,” you are not talking about the temperature. You are saying that you will stay calm under pressure.

Slang expressions also change constantly. Some phrases, like “what’s up?”, have been around so long that they have become idioms, or common expressions where the meaning of certain word combinations are really different from their literal meaning. An example of an idiom is “out of the blue” to indicate something that happened without warning. 

Other slang words are trendy, or come from current music, TV, or movies, and are only used for a short time. For example, try saying Wazzzup to one of your classmates and see how they respond. (They might laugh, and not in a good way.) 

Knowing how and when to use slang terms will help you connect with and better understand American students. As a general rule, you can use slang with your friends and classmates, but should use more formal English when speaking to professors and coworkers. If you use slang in more formal settings, like at work, people might see you as rude or unprofessional.

How to Keep Up with American Slang

The slang examples above are commonly heard around American college campuses, but keep in mind that different areas of the country may use different slang terms. Sometimes, the same slang word may have slightly different meanings in different places. 

Listen to your classmates to understand which slang expressions are appropriate for your area and social group. This can be a conversation starter, too: If you do not understand something, ask!

If you hear unfamiliar slang terms, do not worry. Even Americans are not aware of all the terms and what they mean. Just use good judgment and you will be able to use American slang effectively, on campus and off.
