A word to describe a total douche. This guy is usually the one your girlfriend will cheat on you with. If she's smarter than that, then he'll be the one to coax her into it. A Johnathan drinks heavily and smokes dope 24/7. His music choice is the shittiest of rap. He wears only wife-beaters and sags his camo shorts. You do not want to be around a Johnathan.
God, that guy is such a Johnathan.

Ah, my girlfriend cheated on me with Johnathan!
