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.
1998: OMG I finally downloaded the proggie Magenta. This is so awesome. I'm going to go act like a cock-sucker in some AOL lobbies until a guide bans my phished account.
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
