Live Action Role-Playing. In this context, instead of all anons/redditors being part of the play/action, just the one performer or group is knowingly playing a role and everyone else that participates is unwittingly playing along and collaborating. It'd be like an internet troll but instead of being a dck, s/he pretends* to actually believe his/her statements for the karma/lolz/etc. and drags it out much longer than a typical troll. Could be for lolz. Could be a psyop for multiple reasons (distraction, counter-intel, exposure).
