Lunchbag 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.
Tom: I can't wait for lunch *pulls out lunchbag*

Jim: What do you got?

Tom: Aw man! Tunafish? I HATE Tunafish!

Jim: What a lunchbag letdown.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
