Grumpy Munchkin

Much like a Cleveland Steamer or a Hot Carl, except instead of shitting on your partners chest, you shit on their forehead

My girlfriend said she wanted to kink it up in the sack so I gave her a grumpy munchkin last night.

Grumpy Snail

When one partner lays reluctantly on his/her stomach and is then penetrated in the anus by their partner. Said partner has their back haunched for maximum insertion-giving the appearance of the shell.

"Tina owed me a favor so she let me give her a grumpy snail before we left for the party."
