1. A full-size American automobile produced by Buick from 1936 to 1958 (and briefly revived 1991-1996), distinguished by a rear quarter so generously proportioned that it reads, in raking side profile, less like bodywork and more like a civic statement.
2.colloq. Rear-heavy by conviction, not accident. The haunches on a Roadmaster sit so wide and so low that the front of the car functions mainly as a formality, a nose pointing toward wherever the back half has decided to go.

Etymology:
From Buick (named for David Dunbar Buick, Scottish-born plumbing-parts manufacturer turned engine pioneer, est. as a marque 1903) + Roadmaster (compound of Old English 'rad', meaning a ride or journey, and Old English 'maegester', meaning one who has authority). The name was intended to suggest mastery of the road. The rear bodywork suggests mastery of the road, the adjacent road, and approximately half of the road after that.
Yes. Buick Roadmaster was admitted to the Thiccctionary on July 31, 2026 and filed in the Vehicles & Transport section. The ruling on file: Admitted. Every subject in the catalogue is judged on its curves, not its size.
