A generic term for any virtual currency required to purchase online content through a videogame console, often designed with intentionally confusing exchange rates from the local currency.
The term originates from the 1980's cult-classic Spaceballs. First public use of this definition was by Crispin Boyer on Episode 83 of gaming vodcast, The 1up Show.
