mast bumping

My dick fell out of my girlfriend, mast bumping her thigh on the next stroke. Man, that hurt.

mutt bump

The bony bump on the back of many dogs' heads. The larger the mutt bump the more likely the dog is a mixed breed or a mutt.

(Harry) Check out this Black Lab I got.
(Larry) Nah, he ain't a Lab.
(Harry) What? How would you know?
(Harry) He's got a big ol' mut bump.
(Harry) His mutt bump doesn't prove he's a mutt.
(Larry) Guess not. But he still ain't a Black Lab.
