/frob/ 1. [MIT] The TMRC definition was "FROB = a protruding arm or trunnion"; by metaphoric extension, a "frob" is any random small thing; an object that you can comfortably hold in one hand; something you can frob (sense 2). See frobnitz.
2. Abbreviated form of frobnicate.
3. [MUD] A command on some MUDs that changes a player's experience level (this can be used to make wizards); also, to request wizard privileges on the "professional courtesy" grounds that one is a wizard elsewhere. The command is actually "frobnicate" but is universally abbreviated to the shorter form.
