Coolsjes 

The kid who is supposed to be in 7th grade, but is doing pre-calculus and makes you feel like a complete idiot. He is always blurting out random facts and proving that you are wrong. Says "accurate" way too much.

Ethan- "That guy makes me feel like an idiot"
Lucy- "he must be a Coolsjes"

coolsies 

A "cute-ified" term for cool; similar to calling a sip of beer "a sippy of beer".

It's really coolsies that you went to the mall.

Coolsies 

1. A filler word that you say after someone says something kinda cringe and you don’t know what to say.
2. Can also mean, “weird flex, but ok.”

Bob: Bro I hold the Guinness world record for most chicken eaten in a day!
