floss d'oeuvres

The food remnants that are collected by flossing which for the most part are covertly re-eaten by the owner since spitting them across the room would be regarded as tacky and vulgar.

John: Did you just eat the crap you pulled from your teeth with that flossing stick Fab??

Fab: And why not?? No reason to waste a good floss d'oeuvres boy!
