A large, fat, ugly and un-attractive female who preys on drunk teenagers. She waits until said drunk teen passes out at a party where she begins to deliver a handjob to the unexpecting young man. The man then either wakes up and gets rid of the Bandit, or just rolls with it and trys to keep it a secret from all of his friends.
The HJB can also be referred to in numerical form, by using the letters 8-10-2H=8 J=10 B=2
"Oh man, did you hear? Snake got attacked by the Hand-Job Bandit last night!"
"Dont pass out tonight boys.. here comes the HJB."
"Heads up fellas, i just caught word of the 8-10-2 coming to town."
