A penis bandit is someone who strikes with dicks when no one is around. There is a fine distinction between one who will draw penises for pleasure and one who sets a greater purpose to each shlong he draws. The more crafty and devious penis bandit is a person unbeknownst to the victim. The more mischevious penis bandit will strike psychological fear into the mind of his victim. There is often times a greater purpose to each shlong sent to the victim. The true craft of a penis bandit is unknown until s/he chooses to reveal their intentions.
