An expression often yelled by voluptuous women in heat. Meant to convey their rebellious sass, invincibility, and general rejection of white male society. The expression is often utilized in day time talk shows based featuring bootylicious women on quests to find their respective "baby daddies." Warning: Do not mess with this species of female. She will shank you. Also, the phrase rarely makes contextual sense.
Todd: Hey babe, let's go back to my place.
Monica: I ain't yo' ho. I won't give it up that easy.
Todd: Baby, can't I just put the head in?
Monica: YOU DON'T KNOW ME! YOU DON'T KNOW ME! YOU DON'T KNOW ME!
