Mad Dumper
A Mad Dumper is someone who doesn't just poop. He explodes. He leaves a trail of poop everywhere and laughs when people scream. He also asks why corn is always in his poop like it's a side dish.
He pooped on the math teacher's desk and said, 'This is my final exam.'
He pooped in the choir room and said, 'Now you'll never sing the same again.'
He pooped on the floor during a fire drill and said, 'I'm saving the day.'
