Started in Canada, a person who will at any cost go out of their to annoy and irritate people. This phrase originally started when people went around disturbing other random people in public washrooms when they were
taking a shit. Consequently the people that were being disturbed, when
taking a dump, would curse and get angry with thedisturber but they were not in a position to do anything since they were still in the public washroom stall with their pants down when the incident occurred. They were also not quick enough to catch the culprit in time before he or she ran out. When a person runs into the washroom wets toilet paper and throws it over the stall at the person
taking a shit thus gaining a thrill out of it
