It's a new year, opposed to old

I need a good name for my street gang I'm thinking about forming for 2010. I want the name to sound "bad," as in mean or at least confrontational sounding. I need the right name so potential foes hear it and steer clear of our “turf." Upon hearing our street-gang name, I want our adversaries to collectively say to themselves: "whoa, man. Steer clear of these guys.”
