[Becky]

a character from the 2006 movie ATL; she goes by New New when going to the hood/ghetto; she calls herself that because she rocks the new new shit; she is the daughter of a millioner but hides it; her typical ghetto getup is a side ponytail, big bamboo gold earrings with her name in them, babyphat, nikes and a bad fake ghetto accent!
Teenage girls have stolen the name and now are trying to call themselves New New despite not having the wealth to pull off the look.

[Little_Girl]

New pussy. When you meet a girl you really kick it off with and you hit it once and it keeps comin back.
