blacking up

The act of shifting a motor vehicle into reverse gear while on a highway in order to back up and to get onto an exit ramp one has already passed. This term comes from the New York Metro area, where Asians and Caucasians have conducted a nonscientific study by looking to see what the person taking this action looked like only to find that they are black at least 90% of the time.

"Look at this fucking guy blacking up on the highway..."

Black-up

the traffic caused by a group of African Americans blocking the hall and preventing Caucasian students from moving to their next class.

Tom: Dude, why arent we moving?????
Andrew: Man this is the Math hall. This is probably the black-up from all those black guys who walk slowly.
