Pronunciation: Grum-pee. The act of breaking wind; flatulence. A slang term for having particularly foul smelling gas; a nasty stinky fart.

1) Dude, who busted that nasty grumpy.
2) He floated a grumpy in class. Stunk so bad even the teacher left.
3) I suppose if I have to I can live with Bill's farts, but when he floats a grumpy it makes my eyes water and I have to draw the line

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 

A grumpy as per Johnny Depp vs Amberd Heard - "a human being had dropped a grumpy onto the bed" to shit the bed and leave it for someone else to find.

I was surprised to find Amber Heard dropped a grumpy in my bed.
