You don’t have to worry if you hear your teen saying that someone or something is snatched. It’s actually a compliment, and it could sound something like: “I love those sneakers! They are so snatched.”

Big yikes

To use a slang word that we’ve already learned, big yikes is like yikes only extra. Think about how you might use “Yikes!” or “No way!” and then double it as in: “Big yikes! Did you see what Jared just posted on his finsta??”


You monitor your teen’s social media and are probably even connected with them on Instagram, so you feel like you’re aware of their digital footprint, right? Unfortunately, they may have a “finsta” too, which is a secret second Instagram account. This account is hidden from parents and may tell a different story than your child’s official Instagram account.


Flex is the new way to say "show off." An easy way to remember this one is to picture someone flexing their muscles. Your teen might say: “She is trying to flex all over finsta today since she received another college acceptance letter.”

Conversely, highkey is a way to describe something that you really want to emphasize. For example, “I highkey can’t wait for this day to end! I want to scream it from the rooftops.”

Straight fire is otherwise known as "on the up and up" or better than all of the rest. It can also mean hot. Not as in temperature, but as in “That’s hot!” expressed in a positive way.

Spill the tea

If you hear your teen asking a friend to “spill the tea,” it means that they want to hear the latest gossip or story. Your teen might say, “Spill the tea! I want to hear what happened after you left the party.”


Breaker, breaker. This one may take you back to the walkie-talkie days of your youth. CD9 stands for Code 9 as in, “Can’t talk! My parents are here!”


Shook is a way to describe that you are emotionally shaken or affected by something. You might hear your teen say, “I stayed up all night reading that book, and now I am shook.”

Netflix and Chill

This one sounds nice, right? Maybe you’re at work right now thinking of how nice it would be to get comfy on the couch and watch Netflix tonight with a pint of ice cream. When your teen says it, unfortunately, it means that she is using that as a front to have someone over (or go over there house) to make out and possibly more...

I’m not going to use profanity, but I bet POS means a phrase in your mind that starts with the words piece of… Today, POS is a quick acronym for texting or messaging that means Parents over Shoulder. So if you see this one, maybe you should stay near your teen for a few minutes longer.


Sus is short for "suspect" or "suspicious," so this is a flag that some drama may be going down.

Lit or GOAT (greatest of all time) means something happened that is really, really good. It may feel like you just learned a new language, but hopefully this will help you understand at least part of your teen’s conversations. Have no fear because if these slang words didn’t make their way into your memory, your teen will probably be on to the next slang words and phrases before you know it!

Fauci Ouchie

In the time of 2020 slang words related to the COVID-19 pandemic becoming even more magnified in 2021, we, of course, have to account for vaccine related slang entering the English language. A Fauci Ouchie refers to the COVID-19 vaccine with a reference to public health expert and proponent of vaccines, Dr. Anthony Fauci.


The term mittens is getting even more attention after the publication of countless Bernie Sanders’s mittens memes. It’s a descriptive term for something that was not quite amazing, but not bad either. For example, “I didn’t ace the test, but I didn’t fail it either. I guess it was mittens.”
