cracka killers
A group of people who hate whites and would like to see them all die. They themselves are really just a bunch of dumb, non-white teens who think they're tough. In fact they can't kill anybody and the most lethal weapon they have is a BB gun.
Look at that dumb Nepalese kid over there, who is in cracka killers. He makes fun of whites, but he's just a wimp. Someday, people will jump him and all he'll have to defend himself with is a BB gun.
