A shit and run
When someone takes a dump and clogs the toilet like a fat kid on a sugar rush and then runs away like they just stole the last piece of pizza.
My cousin took a shit and ran out of the bathroom before the toilet even stopped gurgling.
At the mall, a guy did a shit and run and left the toilet like a warzone.
My neighbor took a shit in my toilet and ran like he was being chased by a rabid raccoon.
