A coffee bum is someone who mooches coffee from a co-worker or the office coffee fund but never gives any money to the fund or re-pays the person with the coffee.

Their best move is making change with the coffee fund money, then leaving the less than pot of coffee on the burner, until it turns to Carbon-12 on burndown mode and the fire alarm goes off.
