Your momma is so old when her breast milk comes out it's powder.
Yo mamma so stupid she put two M&M's in her ear and said she was listening to Eminem.
Yo momma's so stupid, she steals samples from stores!
Yo momma so dumb that when she was locked in a grocery store she starved!
Yo mama's so fat, when she steps on a scale, it says, "Please step out of the car."
