When you accidently bump into/are in the way of a black girl. Then when you try to say sorry you get slapped in the face with a "[Nigga] Please!" followed by a string of insults including ones aimed at your ethnicity, mom, fashion sense, Etc. And it all ends with a snap of the fingers and a bob of the head and she walks off. Leaving you in a total state of confusion.
> Johnson: Oops!, I'm so-
> Shaquandaya: Nigga Please!, You look like you just came out of the thrift store with yo cheap ass. Yo mom was a poor white trash hooker and you look straight up retarded! Crazy fuckin' crackas, think they can accidently walk into me!
