your mom, insult overused in the common highschool, middleschool, and any such place where kids are found
Kid 1 - What'd we do yesterday?
Kid 2 - Yo momma, it was very good, I strongly recommend it
Kid 3 - *falls over laughing*

(Yes, this is a real example i heard in one of my classes last week)

Someone who is so fat that she has two area codes.
Yo mamma's so fat, I ran around her and got lost.

Funny jokes when someone tries to insult someone else by insulting their mother.
Yo momma is so stupid... when she became a bank robber, she held up the ATM machine at gunpoint.

Unfortunately a pretty bad retort to another person's insult.
Bob: "Joe your memory is about as bad as a goldfish."

Joe: "Yo momma."

1. The absolute BEST retort to any and all insults.
2. The target of many insults. How everyone's mother can be so many things at the same time is beyond me.
1."Hey little boy, CounterStrike is that way. This game is for real players."
"Yo momma"

2."Yo momma is older than you

guy 1:"dude, ur small!"
