boner loaner

a tease; someone who takes something that you have temporarily; someone who is a buzz-kill

Your mom's such a boner loaner

loaner boner

A guy who can fill in for you when your girl wants to have sex and, for whatever reason, you are unable to handle the deed. A guy who will loan you his bone so your chick doesn't trip, and then will leave when the job is done.

Girl: What's wrong baby?

Boy: I don't know...i guess i'm tired or something.

Girl: Should I send dude a text and see what he is doing right now? Maybe he has a loaner boner I can use tonight?
