You crap in a toilet someone uses and don’t flush it while they're away and wait for them to come back and smell the mess

I crapped in my brother’s toilet and left it to smell like a sewer until he came back from vacation.

I made a Grunny in my teacher’s bathroom and she had to clean it before class.

I took a dump in my friend’s toilet and it stank like a million dead rats.
