Reverse Michelangelo 

A shit so sticky that it leaves brown streaks on the bottom of the bowl.

The Reverse Michelangelo I left in the toilet is a real artistic masterpiece.

A dump so toxic and heinous that it takes paint OFF of walls as opposed to putting it ON walls, like the artist did.

"Dude, after that fish taco? I seriously laid a reverse Michaelangelo up on the can."

dump, shit, defecation
