Get hep to the local street scene with The Rap Dictionary. Its Toronto edition gives all sorts of interesting information on local Hoods, rappers, and gangs. The gang stuff is particularly useful, and since downtown Toronto is basically covered by wifi, its a cinch to figure out who the kids are that are shooting at your Beemer, what they're packing , which one is called Ice Bag, which one Yellow Snow, and whether afterwards they can hustle you some ganja or fill your glass pipe.
There are also Calgary, Edmonton, and Montreal editions of the dictionary. Looks like we've got waaaay more gang activity than Calgary...suckahs!
