He's Juntalis. He doesn't like stupid people, and if that is wrong, I don't want to be right.

OP: Shit on bread and feed it to his dog/cat. He deserves it after fucking your girlfriend.

Here is a joke.

When he walks in kick him out and say "I don't want to be your friend anymore" then kick him out of your house.Next walk outside and kick him in the nuts.

the look on his face is muy comico.
