This is another way of saying that someone or something is too much or over the top. An example might be: “She is so extra. She talks about Karen non-stop.” Extra can also be used in a self-deprecating way.


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.”

This is one you may have noticed in many of BuzzFeed’s “article” headlines. "I’m dead" refers to the fact that your teen is laughing so hard about something that she is dying of laughter.

Straight fire

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.

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

These are two different ways to express what you might have meant by saying "dope" or "neat" or "cool" back in the day. 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.
