FATASS

one who must wear thongs because their GINORMOUS bottom does not fit in regular underwear

Since my locker is near the english office, my fatass english teacher can hear everything I say. i.e., "I've had sex in the shower five times!"

An obese asshole.

"Hey fatass, get out of the way so I can eat!"
"But I haven't eaten in ten minutes."
"Oh boo fucking hoo! I haven't eaten in three days!"
"You haven't eaten in three days? Oh my God, you're a zombie!"
"Fuck you, shithead."
"Don't start with me. Compared to me, you're a twig. No wonder you're so mean."
