Done by a ricer after losing a race. It's the racing equivalent of a sucker punch. It goes like this: the race is over and the winning car is slowing down but the losing car just keeps going and flies by at (what seems to them, at least, to be) a great rate of speed.
To drive your car in such a manner as to invite a street race, especially in another area that is commonly known to be ruled by another particular car. Used by gearheads.
also: protruding, protruder
Hey man, that Mustang is totally protruding in Jimmy-Z's turf, where is he?
