a-rex

Slang for Anorexia Nervosia. Used mainly as an insult for friends who believe they are fat and opt to not buy/eat food.

"Thomas, what are you ordering?"
"Meh. I think I'll get a cruton"
"WTF mate? A cruton? what are you a fatass?"
"Don't call me fat!"
"You are fat you A-rex son of a biotch"

This guy has the longest and fattest dong you will ever see and can make a woman orgasm with a single glance. Like legit this guy is sick mans can inhale so much smoke from a spliff without even a little cough. If u ever find a Rex hide your girlfriend and just hand him all your weed cause this mf can smell that shit out like a dogg.
