Muddy Bicycle Tire

When during Anal intercourse (the woman may need to have diarrhea) the male pulls out and smacks his dick on the females back near the tramp stamp area. This will cause a lot of the fecal matter to be flung off and leave a trail of shit up the spine.

you dude i gave that bitch the muddy bicycle tire last night and she spent an hour in the shower trying to get the shit off! hahaha she couldn't reach it!!

Muddy Doody Society

A membership organization in which to belong you must have taken a dump thought to be a clean swiper (little toilet paper used) and found upon said swipe a muddy mess with doody (feces) all over the paper even under your fingernail. Once you experience this you are officially, like or not, a member of the Muddy Doody Society (MDS)

Man #1: Hey man sorry I took so long, thought I was going to have an easy time in there but fell pray to the Muddy Doody Society.

Man #2: Shit man your first time becoming a member of the MDS?

Man#3: Hell no my wife checks my fingernails before we go to bed at night and she makes sure I have my membership card in my wallet.
