A short handsome man with an incredibly large penis who is always the life of the party(usually hated on by men of larger stature). A man who is charasmatic and can use his charm and humor to obtain whatever he desires including your girlfriend.
I was talking to this really hot girl until this jeb came over and stole her from me. When going to talk to women is always good to have a Jeb as your wingman.
