Fish Food 

The thin film of dried shit that flakes off one's penis after not immediately washing your dick following anal sex with a male or female with an insufficiently douched rectum.

Hey Tim, shake some of that fish food off your dick into Rotor's tank, Jamal's cheap ass didn't go to Pathmark last night.
