A saying used when you are so angry that your years of public school bus humility comes out and gives you the urge to punch a former or current busdriver
When Kip got kicked in the dick by Seth , the pain angered him to the point of screaming out, " IM GONNA FUCKIN PUNCH A BUS DRIVER!"
One who's parents or parent drives a Volvo who will also most likely carry on the family tradition of being a prick and driving in a manner that does nothing but piss off other motorists.
Jim "what was that guys issue"?
Terry: "must have been son of a Volvo driver".
