A bucket shitter can be any person employed in the art of drywall or sheet rock. Specifically, the task of applying joint compound, or "mud", to the joints between sections. Usually used to refer to the old and typically French-Canadian or Hungarian professionals.
"That guy is a bucket shitter from way back!" "What a bucket shitter! Mudding those walls like a pro!" "Hey, bucket shitter, mind if I get in there to wire that receptacle?"
