A portmanteau word of "jog" and "juggle." It is the sport of juggling 3 or more objects, preferably balls or beanbags, while running. It is a great sport that takes coordination, endurance, and dedication.
When attempting to deffocate a "snag" occurs forcing you to jog or move in place, thus aiding the release of the feces.
Jogging, shaking and/or moving vigorously during deffocation thus producing a "Joggle Dump". Most likely developed by canines which also partake in walk-a-dumps etc.
