chump·mo·bile
[ˈʧʌmpmoˌbil] (chuhmp'
moh beel)
NOUN
1. A type of full-sized American luxury sedan, usually boxy and
lumbering in shape, stereotypically poorly and unwieldly driven by older
persons at a slow rate of speed. This term is normally associated with
1990s-era Buicks and Cadillacs, although it should be stressed that make
and model alone do not make a chumpmobile.
Origin unclear.
