Kackadouchy
A human so bad they’d make a toilet blush before it got flushed.
My cousin’s a kackadouchy. He tried to play guitar and it sounded like a cat threw up on a trash can.
My boss is a kackadouchy. He thinks he’s a CEO but can’t even fill out a timesheet.
My dog’s a kackadouchy. He barks at the mailman like it’s a warzone.
