This term reflects the compound act of two poor decisions. 1) Using a Port-a-John (Job Johnny, Johnny on the Spot, et al.) 2) Grinding out a depth charge into the murky abyss. For when you choose to do both you are likely to emerge from the compact bowel booth with a set of smurf balls, as your testicles are splashed with a coating of azure hued ass water.
