1. A phrase used as a formal declaration of defeat. For example: "Kenneth replied 'yo mama' when he realized he could not counter his opponent's point."

2. The principle part of a "Yo Mama" joke, usually entailing a description of your mother being so "something" that "something" occurred as a result.

1. Amy: You're so ugly!
Gwen: Yeah, well so's YO MAMA!

2. "Yo mama so fat, the last time she saw 90210 was on a scale!"
"Yo mama so dumb, she thought a quarterback was a refund."
