Pace Fat
A loud, mean comment you throw at someone who did something so dumb it hurts your brain. It makes them feel like they're not even worth your time.
'Pace Fat!' my mom screamed at me when I tried to clean my room by throwing everything out the window.
'Pace Fat!' my dog barked at me when I tried to wear my socks as a hat and failed.
'Pace Fat!' my neighbor yelled at me when I tried to talk to his cat and it hissed at me.
