A crappachino involves taking a shit and then mixing it with milk in a shaker bottle. Then, you put the mixture (which should be a light tan/brown) in a iced starbucks coffee "frappachino" bottle (or a similar iced coffee drink) and attempt to give it to someone, claiming that you bought this and did not want it.

When, after taking a large dump, one sprays a french vanilla air freshener, but it does not cure the stench, but only mixes with the poo smell.
Whoa, somebody made a grande crappachino in here!
