A word I found out about through an interview with Aaron Lewis (the lead singer of the (great) band staind. he was asked why it was called "mudshovel" and he said it was a term for anal sex and h thought it was the funnuest thing he ever heard so he wrote as song about it. The mud being the shit in a girls ass and the shovel being the peins in it.
"dude, I had mudshovel with a hot bitch last night!!!"
