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.
Commonly misinterpreted to describe a homosexual. A 'cockmaster' is actually one who through much training, has mastered the art of seduction. A true 'cockmaster' will be promiscuous and seldom pleasure the same girl twice. Although he may leave broken hearts in his wake, the 'cockmaster' will have no regrets, will never apologise and never look back.
"Mate, did you see that stunner that Duncan shagged last night? He is such a cockmaster"
