i prefer sticking to yo mama jokes
yo mama's so dumb, it took her an hour to make minute rice.
yo mama's so fat, someone told her it was chilly outside so she ran out with a bowl.
yo mama's teeth are so yellow, i can't believe it's not butter.
yo mama's so ugly, she couldnt even get a date on her tombstone.
yo mama's so hairy, she looks like she's got don king in a head lock.
enjoy
oh yeah, i also like saying... YOU'RE A WASTE OF SPERM
can't beat that
