rustic waterfall

when you go to someone's house (preferably someone you don't like too much) and you take the top part off of the toilet and take a dump in the tank. from then on until the owner of the toilet discovers the dump, the water that comes out when you flush it will be a wonderful "rusty" brown shade.

"dude i 'rustic waterfalled' that broads house after i found out she cheated on me. the toilet still drains turd water."
