Taking a dump in a bathroom and leaving without wiping. Flushing is optional.

A minute or less dump. So quick you literally jump up when finished. As if in a hurry.

The dump n jump is employed when you are low on time and still need to poop and shower. It’s when you turn on the shower to get warm and in the time it takes to warm, you take a dump. Immediately when the dump is done you “jump” directly into the shower without wiping.
