OPP 

A female/or male who acts like a idiot, mentally slow. May share a common ancestor with the sloth off of the movie “ice age” (Share the same characteristics). They also talk shit, act hard and claim they real, but in reality they talk bout their closest friends. Finally they don’t know who or what they want in life.

Mostly guys with the letter J in their name like the most popular one is the name Jordan. Then you have Josh, Jayvon,Jaseer, Jason, Jayden, Junior. Jordan is an OPP
