powerdump 

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. When taking a powerdump, it is not unusual to firmly grip the underside of the toilet seat to maintain stability.

Man, Rick had to take a powerdump last night, and he ended up spewing crap all over the place before he could sit down. Now my bathroom's ruined.

Powerdump 

A kind of dump when one has to quickly enter and exit the bathroom. Aside from the speed, it is no different from a normal dump. No corners may be cut to reduce the time.

Guy: "Dude, they'll deduct minutes from my paycheck if it takes me longer than a minute to go to the bathroom."

Friend: "Looks like you need to take a powerdump"

To squat down and allow the fecal matter to come out of your ass.

To clean the colon.

Did you see Dave on tv last week? No what happened? Dave came out, squatted down and took a massive powerdump all over the place.
