What is Get Up Out My Grille?
1.
Very similar to "Get up off my nuts", but it can be used by persons of both genders.
Rooting from "Cease and decist" it has been urban-ized and turned into a more popular version.
Exacting meaing is not known, but when it is said, it is advised that one moves up out the "grille" or personal space of the one who said it. Not doing so could lead to the "busting of a cap"
Herbert: "Hey Phillip, get up out my grille a afore I bust a cap in yo ass."
Phillip: I shall cease and decist.
