Grumpy Customer

A really big dump, that may or may not be currently slamming against your rectum.

Hey guys, I'd love to help you, but I've got one hell of a grumpy customer right now. It requires my full attention.

Tom: I’ve had bad farts all day.

Jim: oh, I agree grumpy buns.

The Grumpy Dan

When one male angrily has sex with another male from behind, the giver gets a little grumpy and reaches around and inserts his pinky finger into the urethra of the male he is also penetrating.

Dude I can't sit or pee this morning, Rudy must have been in a bad mood last night as he gave me the Grumpy Dan.

Grumpy dumpy

When you let a shit go and it was not refreshing and you regret letting it go.

I just shitted my pants that shit was a grumpy dumpy.
