used to be ocean Pacific back in my day and a couple other things.
Now I'm hearing "dude is OP as f*ck"

op 

Overused word by most people who don't even know the meaning of it and use it in the wrong context.

Some people even use it to start their own sentence while talking casually.

OP = Overpowered

Term started from video games that make something or someone better then they are actually supposed to be.

Wrong ways to use it:

My iPad is so OP!
Yo OP! Lebron James is OP!
Correct way to use it:
This card in MyTeam is OP! He isn't this good in real life
