Yo mama so fat, she made a monster truck to a low rider. Yo mama so nasty, when she eats a burger, it's like watching Jurassic Park. Yo mama so stupid, she got fired from a M&M's factory for taking out all the W's.
idk if its been posted yet as so many post so far but one of my best jokes to burn people with "yo momma like a mcdonalds cheeseburger full of fat and only worth 1 dollar"
