O by the way it is the but not the back idiot
I got one, You mama so old, when she farts dust comes out.
Some were ok, but most were lame.
the roll one is the only funny one to me
heres a funny one:yo mama so fat she wore a yellow dress and people yelled "taxi taxi"
YOUR MAMA IS SO UGLY SHE PUTS LIPSTICK ON HER HEAD TO MAKEUP HER MIND
yo mommas so ugly that when she stuck her head out the window she got arrested for mooning
yo mommas so fat that when she swam in the ocean the whales started singing "we are family.."
yo mommas so fat that when she wanted a water bed, the navy put a giant sheet over the atlantic ocean
yo mommas so stupid that when she worked at an m&m factory, she threw away all the "W's"
those were that funny but iz ok
