Shifty Shekel Pebble Bandit

A Shifty Shekel Pebble Bandit is a person with disposable cash and means of hiding their identity who spends their free time pelting homeless people with spare change.

"Hello sir, can you spare a...OUCH!" said the man, whose bad luck and tattered clothes only served to compound the shame of being struck yet again by the local Shifty Shekel Pebble Bandit.
