We had a fucking legend shit in a teacher’s trashcan when the teacher wouldn’t let him go to the bathroom. Teacher was one of the infamously strict “zero bathroom breaks, you should have gone before class and can hold it until afterwards” types. So after asking a few times and getting denied, the kid just dropped trou and squirted molten hatred into the teacher’s desk side trashcan.
And yes, the teacher changed his rule following the incident.
