I mean, we've all done it, accidentally walked into the wrong toilets. But, while it might normally be an "oops" and walk out - Cate McQueen and Rosarosebud are not going to let him walk out after catching them pissing! So they drag and kick him into the cubical, and wedgie his pants before flushing his head into the pissy pan. And this is only the start of the torment! More and more headflushing, spitting, kicking, slapping - more wedgies! He thinks he's being allowed out of the toilet only for Rosarosebud to spit her chewing gum onto the floor, trample it under her trainer and have him chew it from her trainer. His head is pushed to the dirty floor as the two brats bully and spit on him. This is harsh humiliation as the two torment him before sending him back to the class a mess, and still, presumably, needing a piss!
