She jokes

Yo mama so ugly that when she watched The Outsiders, they became The Insiders.

Yo mama so strict that when Ponyboy told her that Darry hit him, she called the cops on Darry.

I saw a fat woman at the bus stop today, so I asked her, "When's it due?"

She replied, "I'm not fucking pregnant, you rude prick!"

I said, "I meant the bus, you fat cunt!"

Your mom is so fat, she starts the alphabet with the letter "o" for obesity, hahaha!

Your mama's so fat that she can’t even talk, even if Kevin says, "Oh my gosh!" 'cause she has a big ass mouth.
