look up any word, like dirty sanchez:

A stinky tulip is when vigorous anal intercourse causes the recieving partner's rectum to prolapse, revealing the reddish pink rectum. The transverse folds of the rectum make it look much like the flower of a tulip with the stem shoved up your partners anus. It also, because of its location, is almost always stinky.
"I rode my girlfriend's ass so hard that I finally got to see her stinky tulip" or "Josh, even though you've never given me flowers, your stinky tulip is the gift that keeps on giving."
