When a friend axe's you something, and you were obviously going to do it, you state "Nigga-Please!" to express the shame you feel at having such an insult to your honor.
Lysol: We gonna rape some bitches tonight?
Lyrese: Nigga-Please!
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!
Johnson:...What just happened?
When you fail at something in life (eg. failing an exam or not getting a job), go home and spend an hour just standing in the shower, propping yourself up against the wall with your eyes on your feet.
Caleb knew the only thing to do after he didnt get prefect was take a failure shower.
