grump 'o' lantern

The act of receiving head while shitting-except instead of shitting in a toilet you shit into a jack 'o' lantern. Most often occurs around Halloween

Dude I ain't gay or nothing, but that 11 year old boy dressed as Frodo just gave me a wicked grump 'o' lantern. Good old Jack now has a shit eating grin-literally. Happy Halloween!

Grumpley

The mood/feeling/state of mind when you know, in retrospect, that the activity you are doing will be fun.

I was a bit grumpley when I was walking up that hill, but really it was fun.

grumpgasm

A grump so good, you feel like you just blew your load.

After eating a Ribeye, two baked potatoes and a salad last light, my grump this morning was so awesome, I had a grumpgasm.
