When someone interrupts you while you are enjoying a bowel movement in a toilet stall.
My friend anthony was dethroned at Bogarts when a stoner had the runs.
when someone with a bad case of the runs throws you off the crapper mid-dump.
person 1: hey why u so sad
person 2: some douche dethroned me a while ago
person 1: well it seems somebody's having a crappy day
