A very mean person who tries to ruin your life and invades your privacy by doing rude things because she doesn’t like you very much even though she had sex just so you can come out her vagina unless you were an accident
Eric: Hey who is that privacy invader over there?
Delta: Oh that’s yo momma!
Yo momma-
used as a cool slang or a comeback when you don't know what to say. Or you can endlessly troll people.
Yo momma so fat, she went to kfc and said "can I have the one on the roof?"
Jonas: Hey Zach, what do you wanna do tonight?
Zach: yo momma
Jonas: stop
Zach: if you don't shut up ill do you instead
( ͡° ͜ʖ ͡°)
also you can do this:
Issac: yo momma so thicc she can't fit in you'r closet so she can hide when shes a lesbian.
The female under my desk currently
Person 1: hey, who are you
Person 2: the dumbass on urban dictionary’s mother
Person 1: ok, get back to ‘work’ *winks at camera*
Yo momma
You know the woman who birthed you
Yo momma again the woman who f*cked your dad and had you the accent
