Jimmy

A huge asshole that enjoys making fun of his closest friends, to the point of them losing them. He is a loud-mouthed dickhead, usually with a very small penis. A Jimmy will also usually assault his friends to the point of pain. Stay away from any Jimmys you know.

"Ugh. There goes Jimmy."
"God Jimmy is such a dick weed!"
"Come with me. Jimmy is over there and I don't want to go near it."
