a "heckletwizzler" is someone who likes to wind nasty words or phrases into anyone and everyone while driving on the road.
I was sat next to this guy who had been dishing out a stream of nastyness when this goriller came over, so he did his window up and shrank into the drivers seat,

well i just though what a "heckletwizzler."
