To Beat the bandit, is too take ones penis and begin to jerk like normal, and then increase in speed until you are in physical pain and/or have drawn blood. It is often considered a punishment wank, post getting with a munter.
Bret: "Yo bro I had to Beat the bandit last night"

Mike: "What why?"

Bret: "I got with some skanky bitch, had to teach it a fucking lesson"
