Y-Block Blood Niggaz
From Rap Dictionary
The YBN are a small territorial African-Canadian street gang whose members hail from a housing complex on Yellowstone Street in the Jane and Finch community of Toronto, Canada. As indicated in their name sake, the YBN claims the Down-Bottom "card", like many of the housing complex south of Finch Ave. West. Its members range in age from their early teens to mid-late 20s and come from different ethnic backgrounds. The Y-Block Blood Niggaz are rivals to all Up-Top Crip sets, in particular, the Up-Top Driftwood Crips and Up-Top Shoreshot Crips.
