lurker

A guy who hangs around your girlfriend as a "friend" who is really just waiting for the day when you and your significant other are on the rocks. That is when he swoops in to make a move, as the comforter, supporter, and basher of her current bf. Women are oblivious to them entirely.
Oh you need to talk to Matt? Jeeze that guy is such a lurker!
