(Internet, uncountable) Cybersex in a multi-user dungeon environment.
One notorious trick in less reputable corners of the MUD universe is to talk somebody into going into a dark corner of a MUD for some tinysex — dirty talking via computer screen, within character for the MUD, along with explicit posing — a dark corner where some invisible wizzes are hiding.
