Mudface 

A mudface is something that only a very sick or filthy woman would let you perform. The quintessential smut peddler's paradise. It involves showering a bitch's mush in shards of gooey shite, preferably with the velocity of a shart. Once applied, the woman leaves it to dry on her face before flaking it off like mud and using it to top a cappuccino.

Pascale "So are you gonna give me a mudface or what?"

Me "Umm, do we have to? Can't we just make normal love?"

Pascale "Are you gonna dump on my face or am i going to have to try and shart on my own face?"

Me "OK, here comes the dumper truck..."
