A stadium appetite

When you go to a sports stadium and order: a plastic cup filled up way to high with bad beer, a bag of unsalted peanuts and a hotdog with a way to short bun.
Afterwards you’ll have diarhea in a stall with no door while 20 guys wait for you to finish.

Person1: yeah... I’ve got a stadium appetite
Peson2: ohh... really. Good lick man...

Stadium seat

When your butt tingles from sitting on a hard surface for too long.

I don't want to go to the football game, I get stadium seat from sitting on the bleachers.
