Hangoff

That person that hangs out with you but doesn't. When your in public that person is there but will sometimes wonder away and then come back when they want other people to think they have friends. Usually this person has no group out side of this group they "hangout" with. They are socially hanging off your group and your friends. They do this to seem higher of in the social hierarchy. This is sometimes referred to as a third wheel but in this case the person isn't invited or wanted at the group events. Try not to wear it out.
