To fuck a fat chick, usually to distract her while your friend tries to score with her hot friend.
I was playing wingman when Dave hooked up with Kelly, so I had to jumbone her friend.
a. a really large boner
b. a puppy chew
Man, that girl with the pert rack gave me a hell of a jumbone.
The man threw the jumbone at the dog's head.
