A slang term for program. This term was popularized in the 1990s on
AOL when kids would create third
party programs designed to exploit
AOL software. Underground sites would entail the swapping of "proggies" and "punters" like Fate, Havoc, Blue Cross, and MiB. These were designed to paste text macros to disrupt chat rooms, crash other people'
s computers (and sometimes your own), and cause all other kinds of mischief.
