An obnoxious alter ego involving douchebagness. "The Jeff" always refers to himself in third person and loves to talk about only the following things; gym, protein bars, working out, hair gel, his love of the show "Friends", fighting, degrading women. The female version of "The Jeff" is "The Rach". Similar to a douchebag but not constantly.
