Obvvz!
A loud way of saying you're so dumb you think the sky is green and the sun is just a really bright person.
Obvvz! You tried to cook dinner and set the kitchen on fire. Are you a chef or a pyromaniac?
Obvvz! You said you'd finish your homework. It's still in your backpack. You're like a ghost who forgets to haunt you.
Obvvz! You called your teacher a donut. And it was a Monday.
