The muddy sheets is an exotic and erotic sexual maneuver, involving a man, woman, and the man's best friend. You begin by fucking your lady friend in the ass via doggy style while under the sheets of your best friend's bed. She begins to get tired out when you donkey punch her hopefully initiating the washing machine. IF the first punch does not grant the desired effect, punch repeatedly. Mid seizure she will begin shitting all over the covers, in which case you GET OUT OF THERE. Make sure to yell as loudly as possible when running away, kind of like a dying goat. This will create the muddy sheets effect for your best friend when he comes home and finds a passed out chick in a shit covered bed. Bon apetite!

When a guy is comfortably reclining (on a bed, in a chaise lounge, or any other suitable seating device) with a raging throbber, and his lady-friend walks into the room, coyly strolls up to him and his veiny bastard, and acts as if she's about to sit on his dick, fulfilling his wildest sexual fantasies. HOWEVER, instead of gently lowering herself upon him, she takes a gigantic, steaming shit on his member, and triumphantly walks out. Thus, the man is left with blue balls covered in a pile of steaming, brown mess, and the woman emerges victorious.
Samantha saw her boyfriend make out with another girl at the bar, so when she and her boyfriend got home, she gave him a muddy throbber.

When someone fails to flush the deuce they dropped in the public toilet, and then subsequent users of the toilet, rather than flushing it down, continue to urinate on the floating turd until the surrounding water becomes so murky you can only barely see the top of the log emerging from the water.
