Food for thought, in a literal sense. It is food whose purpose is to fuel a late night study session or any other situation in which the brain is actually to be utilized.
Often used ironically to describe food eaten for a situation from which no good could ever come.
I've got to write this fucking term paper by tomorrow. Go down to the T-bell and get me some goddamned Brahmin noodles, yeah?
Picking up some Brahmin noodles for the cow, then it's back to my place to fuck her to sleep. I sense that the sun will bring regret.
