frob: /frob/

1. n. [MIT; very common] 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. vt. Abbreviated form of frobnicate.

3. [from the MUD world] 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.
