Shump 

A shower and a dump at the same time. Shumps usually take place in the handicap showers at the pool that double as toilet stalls. The shumping process usually consists of the subject stripping down naked, grabbing the detachable shower head, and holding it over themselves as they drop logs. It's also environmentally friendly as long as you're not in California because the shower head can double as a bidet.
