a girl like J Lo who used to be from "around the way" but blew up and is big, just like her booty. Unlike J Lo, roundaway girls are still wholesome and sweet, not diva bitches.
Have you seen 'em? Those roundaway girls with the big booties and the stink? They need to wash they ass.
Person 1: J Lo is a roundaway girl.
Person 2: Hell no, that bitch think she's all that.
