A boyfriend who is so infatuated with his significant other that he does not realize that no real chemistry exists between them, or that he serves only as an object to be exploited, especially as an apparatus upon whom she may hang her purse should she desire to ascertain the fit of a particular garment.
Guy #1 "Dude, did you hear Alex and Kayla are going out?"
Guy #2 "Dude, she doesn't even like him, he's just her purse hanger"
Guy #1 "Yeah, but he doesn't care, she's like the hottest chick on this side of the Appalachians"
