Snacks

The tiny bits of food, crumbs, and sauce drips from recently eaten food that get stuck in a bra, long hair, beard, moustache, chest hair, shirt, bedsheets etc.
Snacks may be flicked away, washed off, or especially eaten when noticed.

"I was motorboating my girl in the theater and I found snacks in her bra"

Dude 1: "Hey man, you have snacks in your beard"
Dude 2: "I was saving them for later"
