Schultenbräued
A Dutch-German practice, where one shaves his treasure trail (A line, bar or tuft of fluff on a man's belly, between the belly-button and the top of the pubes) and put it on the pillow of someone else. Often performed at sleepovers. Said to bring good luck to the person sleeping in it.
That's why I never want to fall asleep first, you might get Schultenbräued......
