bumpump

To inflate a woman's anal canal by pumping one's phallus in and out. The air pressure created by the pumping will result in a massive expulsion of the air once the phallus is removed.

The expelled air often has a minty aroma and tastes mildly sweet.

1. I bumpumped her and the sweet essence of heaven was emitted.

2. She was bumpumping me while i bumpumped the hell out of the girl in front.
