A former NBA basketball player known around league locker rooms as having the largest cock in the league. As a verb "Detlef Schrempfed" or "schrempfed" or "D. Schrempfed" refers to being royally fucked as if by the largest cock imaginable.
I was in a bar and this girl "Detlef Schrempfed" me in front of my crew when she laughed after I asked her for Chili Dog sex.
Before going down on some chick, insert one digit into her poon tang and figure out a way to smell your finger without her noticing. This way you know if it smells like dead mice down there!
Man, it was a good thing I gave your wife The Shempf Test, it smelled like a homeless dudes chode down there!
