a versatile interjection with a dual meaning:
(1a) "Sweet!"
(1b) "At the present
moment, I have a commanding
grip on your genitals."
(1b)'s usage is usually figurative, and is best used to express temporary and unearned dominance over another
individual.
Rosie: "Dogg, I just got dinner with mad
bitches and one them didn't finish their lasagna, so I brought it home for you to eat."
Yoshi: "Rapzini!"
In this instance, the reader is left to determine whether Yoshi is expressing delight over procuring free lasagna, or a sense of smugness and superiority in light of (a)
Rosie's dutiful gesture of bringing home the aforementioned lasagna and/or (b) Rosie's intellectually bankrupt choice of the third person plural possessive "their" in describing a single bitch.
