Frobnitz, pl. Frobnitzem (frob'nitsm) n.:
An unspecified physical object, a widget. Also refers to electronic
black boxes. This rare form is usually abbreviated to FROTZ, or more
commonly to FROB. Also used are FROBNULE, FROBULE, and FROBNODULE.
Starting perhaps in 1979, FROBBOZ (fruh-bahz'), pl. FROBBOTZIM, has also
become very popular, largely due to its exposure via the Adventure spin-off
called Zork (Dungeon). These can also be applied to non-physical objects,
such as data structures.
