That's so gay! 

A commonly misused phrase by many people (mostly children between the ages of 9-17) that use it as a bad thing. In reality, it's meant to be used as a good thing. Gay means a homosexual person (gay is also used as an umbrella term for the LGBTQ+) or happy. Happy is a positive feeling.

The phrase is meant to be used as something someone likes, not what is seen as weak or girly or bad.

Sally: Did you see what Chris is wearing today, he is sooooo hot in it. I mean look at that jacket!
Holly: That's so gay!

John: I know, he's the coolest guy around!
