Yo mamma so stupid she put two M&M's in her ear and said she was listening to Eminem.
Your momma is so old when her breast milk comes out it's powder.
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."
