An endless series of jokes beggining with "yo momma so..." and ending in a custom punchline. jokes include, but are not limited to:

Yo momma so fat...
Yo momma so dumb...
Yo momma so ugly...
Yo momma so slutty...
Yo momma so old...

You have to make yourself sound black when you say them. It doesn't really make them funnier or less annoying, that's just what you have to do.
common Yo momma jokes:

Yo momma so fat, she walked in front of the television and I missed three commercials.

Yo momma so dumb, she stared at the orange juice carton because it said "concentrate."

Yo momma so ugly, when she tried to pay the male prostitute to bang her he looked her up and down and said "No way. Even sluts have standards."

Yo momma so slutty, even Snooki can't keep up.

Yo momma so old, Jesus was in her yearbook.
