bang bang 

As said before, a phrase used by emos/scenesters on sites like myspace...and also as a stated before it is accompanied by a crappy graphic of a gun, which is usually a pistol (more specifically a berettta 92-fs for some reason) or and m-16 or ak-47. These graphics will always have one or more of these characteristics:
-glitter
-blood or some other liquid dripping out of the barrel
-a rose protruding out of the barrel

I wish emos and scenesters really would put a gun to their head and pull the trigger...happiest *bang bang* I'd ever hear!
