Blackup

When an altercation occurs between two or more persons of non-European descent, a third party will call a relative or friend. Once the call is made, three or more vehicles will arrive instantaneously to render such assistance as needed to the caller.

Woman 1: "Bitch, don't you lay a hand on my fucking child!"

Woman 2: "That Hoe fucked my Man!"

Crowd that gathers instantly: "Oh snap!"

Woman off to the side: "Shit is going down, I'm calling for Blackup.", {on phone} "MMMMmmmmmHHMMMM~!"

Instantly, cars full of people appear. Scientists believe this phenomenon to utilize what they call "Black-Holes".
