1. The kind of dump that if at work going to the handicap stall is a must as the bars are needed for extra grip. 2. A massive explosion of fecal matter that splatters the porceline toilet and shoots up towards your balls, vagina or butt. 3. A dump that when completed is well worth bragging to your friends.

A common variant of dump, the powerdump often occurs when one has diahrrea, has eaten something just a little too spicy, or has held it in just way too long. According to extensive reasearch on the powerdump, the majority of people who undergo it often say that it is one of the more unpleasant kinds of dumps.
