The state of one's digestive system after a night of drinking lots of beer. It is a prolonged period of beer shits, and is characterized by repeated heavy shits, that take forever to come out, and leave greasy streaks on the bottom of the toilet.
I got hammered last night, and I've had the grumps all morning.
Man, somebody must have the grumps; I can smell it from here, and the toilet is shit-stained.
I had the grumps this morning, and I feel about 5 pounds lighter now.

A motherfuckin' grumpy-ass dog. He's always grumping and being rude. He doesn't have anything to grump about (except maybe that our McDonald's doesn't have $1 McDoubles) but he continuously grumps. Also a cheapskate and is not forthcoming with kisses or snugs.
Zack: Hey let's go smoke synthetic marijuana!!!
Em: I can't. I have to take this Grump Grump to the vet to get this cone off his head. He's grumping about it.
