Wet German
A sexual act involving a burly, bearded German who has had a meal of sausage and beer, and has the juices from both caught in his facial-hair. With these juices covering his beard and mouth, the German performs fellatio on a woman, coming away with a sloppy-mix of food and sexual liquid on his face.
"Did you see all that weird, greasy crap in his beard? That guy looks like he gave a wet German!"
