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.

Tim: "I was taking a massive shump. Dude, my asshole has never felt cleaner."
Jake: "Holy bejesus, I gotta try that some time!"

When you cum on someone (face,mouth,etc.) and the partner wasn't expecting it and in a fit of rage collects the cum in their hand and then slaps the other partner in the face.
After I busted in her mouth she spat it into her hand and shumped me in the face.
