Acronym for: Pimp Behind The Wheel. Similar to the HMFIC or HNIC, except that the a PBTW doesn't need to worry about supervising anything but his bitches and keeping his chrome wheels nice and shiny.
Check out those bitches! They let themselves out of that fly ride to walk around and open the door for their PBTW.
