look up any word, like blumpkin:
Any truly disgusting drink from Starbucks.
E.g. "Vanilla" Frappuccino.

Actually it doesn't have to be from Starbucks, just some high end coffee place.

a shake made of peanut butter, chocolate syrup, vanilla ice cream, and milk. either hated or loved, and often called a "shit shake" because of the disgusting appearance. add a banana for texture.

when you are making a chocalate shake for your friends; you add milk, chocolate ice cream and then you add a nice footlong turd. And to top it all off you put some whip cream and a nice little cum shot on top.
