Toilet Owl

Toilet Owl is the type of person who somehow manages to besmear the walls of the public toilet cabinet with his/her own shit, as if he/she was an owl, defecating while positioned on top of the cabinet wall.

The following conversation takes place in the high school principle's office:
Pissed off freshman: Mr. Principle, the toilet walls are covered with human shit!
Principle(whispers to himself): Goddamn those toilet owls! Honey, where's my Owlkiller5000?
