Mix up a grumpy

To defecate. To take a shit.

Man, I really have to mix up a grumpy.
Hold on while I go mix up a grumpy.

grumpy

Grumpy - als in grumpy old men

BBC program Grumpy Old Men -
50 year olds moaning about society,
from cell phones to litter on the streets.
Very humorous. Not at all the sexual connotation!

Grumpy Cat

When you tie up a girl and you're going down on her and she's just about to cum and, just before she does, you pull away and quit and "meow" like a grumpy cat.

This girl was so pissed because I gave her the grumpy cat.
