A bonerdoner is a guy that a girl, usually very attractive, elects to have pre-arranged sex with her one or more times just to get over a relationship/bad test/daddy problems or just because she is extremely horny at the moment. A bonerdoner differentiates from a fuckbuddy in that they do not necessarily have to be friends, nor do they have to have sex more than one time.
Julia: So, did you get a bonerdoner for the big weekend?
My wife: “If I ever have sex with a lady I’ll be confused and wonder where her penis is.”
Me, an intellectual: “No you won’t, you’ll just pull one of yours out of your bonerleer and use it on her.”
