Your girlfriend's "Guy Friend" who never chooses to talk about you with her, comment on pictures of you and her, and never ever makes an effort to meet you. The worst part is, your innocent girlfriend will always deny and defend him because he's seemingly so "nice and friendly" when you call his actions out.

He's the Punk Bitch who secretly loves your girlfriend and will strike at any weak moment in your relationship.
