Steve: "I thought I'd picked up a good fuck for the night then I suffered Lunchbox Letdown."
A lunchbag letdown occurs when something you had been looking forward to turns out to be far worse than originally anticipated.
The term originates in the lunchroom (be it school or office or otherwise) where after a long hard day someone sits down with their lunchbag hoping for something tasty. Instead they find something unappetizing, whether it be the wrong lunch, it's moldy, it's cold, or any other multitude of problems.
After such a situation, it can be said that your lunchbag was indeed a let down.

They will kick his ass and send him home crying to his white grandma.
