That person who, when someone is using the restroom for an extended visit (#2), continuously rattles the doorkonb, bangs on the door, and/or yells "watchya doin in there?".
The objective of this rude assault on a person at their most defenseless moment is to make the victims dump unrelaxing and stressful as possible. Extreme heckling can at times prevent poo entirely, leaving the victim at risk of a hershey squirt later on.
The Poo Heckler most often lurks around offices or other densly populated areas, preferably with small, single occupant restrooms. This enables maximum humiliation and discomfort to their victims.
Poo Heckler is not to be confused with "dump cheerleader" or the infamous "turd burglar"
"i was taking a nice relaxing dump, but Jamie kept banging on the door and rattling the doorknob. What a total poo heckler!!"
