Created by JiM while he had laryngitis, J.O.S.I. Stood for "JiM's Optical Speaking Intelligence". J.O.S.I. was used during live streams on Twitch in order for JiM to continue his weekly stream and still communicate with chat. But things change and so, J.O.S.I. will probably stand for "Justly Obliterate Senseless Imbeciles". Seems more appropriate for a deceptively cute killing machine.
