look up any word, like fap:
Derogatory term for a rebranded underpowered General Motors vehicle having the improper brand of PONTIAC.

By definition, although misleading at times, PONTIAC is GM's vehicle excitement division. One such paradox was the Pantiass Aztec; essentially an uglified Buick Rendezvous which stirred little excitement amongst the normal public.
Vehicles worth of the Pantiass brand are the Aztec and the Sunfire.
