Dignity Ditch

The art of observing a man or woman's entry into a toilet stall followed by silence indicating that they expect said person to leave. Only, one pretends to leave by opening and closing the door yet remain inside allowing the subject a false sense of privacy. Upon forceful evacuation of the bowels and much flatulence said observer involuntarily commences hysterical laughter thusly devastating any sense of dignity said subject had before entering the stall followed by immediate egress with a great sense of joy at another's expense.
