rack snack

A collection of crumbs and other fallen food particles collected in the cleavage of a large-breasted woman.

After my wife messily consumed a loaf of crusty bread, I removed her tank top and found she'd accumulated a nourishing rack snack.

Snack Rack

The term used to describe the rack of a female (ie. a twinkie tits) used to store snacks.

The girl thought to herself "Wow, i'm hungry.", then she reached into her snack rack and pulled out a cheese danish.
