shortened version of "Bronxville".....where white people hang out pretty much. Everyone that lives there pretends they're hood and from Yonkers but are actually waspy yacht owners who push BMW's paid in full by their parents - who work on wall street... young high schoolers like to go there to smoke weed and shit...
white kid: yo wanna go to BXV?
white kid 2: sure i have a dime in my bag
BXV kid: yea i'm from yonkers hood, get at me niggas
yonkers kid: Nigga you're from BXV, fuck you
