When you are having sex with a girl or guy and they shit on your balls, covering it in poo. Aka Mudding the Pigs.
Nimfae was being fucked by Sealreth when he pounded her vagina so hard she shit on his balls. She loves to mud the pigs!!
When two gay males roll around in their steaming liquid shit and wear pig masks and one the of males freezes part of the shit and proceeds to shove it up the other males ass for sexual gay lover pleasure whilst rolling around in the shit.
Ivan: Wyatt and ace just did a Frozen Danish mud pig last night!
Jack: We gotta try that sometime!
