@Lordyaswas,
I lived in a dorm at college, our bathroom had 2 stalls for 8 girls.
One day I came back from class, and 2 of my suitemates pushed me back saying, "we have to go someone else, NOW"
Seems maintenance had been called for a clogged commode, and no one wanted to fess up to what was found.
A pair of panties, and a fork.
To this day, I have no idea.
