The act in which one defecates into a womans mouth, and while still open, dexterously spins around and ejaculates into the victim's mouth. After orgasm, the man uses his still-erect phallus as a "blender" to swirl it around into a nice frothy, foamy german milkshake.

John D- Oh shit! So a second date lined up?
Glaser- No, she actually choked on that mess and died.
John D- Damn, respect!
