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.

Taking a dump and a shower in the same trip to the bathroom. This is for maximum efficiency and cleanliness, as one leaves the bathroom with a clean ass and maintains that cleanliness until tommorrow's shump.
