Jambone

To get jerked off very aggressively, with the the giver jamming their fist against your pubic bone and maybe even jamming your pecker in their mouth if you’re lucky. Historically underneath a table while trying to hold your composure among unknowing company.

“Hey, Lenny looks a little flushed, I think he’s having a panic attack.”

“Nah man, Linda is just under the table giving him a really solid jambone”
