shit mummy

When someone likes to get shit on in sex (insanely gross) the person getting shat upon is the shit mummy.

Mummy Shit

After taking a painful shit you end up walking like a mummy and/or zombie in order to not upset your asshole.

Wife: Are you okay dear?

Typical guy/husband: Yeah but I just took a big Mummy Shit and it hurts so bad!

Wife: Pig.
