2. Milk dripping out of someone's ass after some dodgy goings on

1. "Oh yes! Look at all that Anal Milk!"
2. "Why is all that milk up your ass?"

Anal milkshake 

Watery and often violent diarrhea. The sound of excreting said milkshakes in public restrooms can often be mistaken by other patrons as that of someone vigourously mixing actual milkshakes (Unless it is accompanied by screams or loud groans of agony).

I'm sorry, we're out of milk, but, if you like, I could make you an anal milkshake.
