The Flintstones were a prehistoric animated sitcom of the 60s. Kind of like the Simpsons. Fred Flintstone's catchphrase was Yabba Dabba Doo! Which sounds like "Abu Dhabi do". That's possibly the worst Flintstone joke I ever heard.
In most English-speaking countries, the French spelling coupé and anglicized pronunciation /kuːˈpeɪ/ koo-PAY are used. The stress may be equal or on either the first or second syllable; stressing the first syllable is the more anglicized variant. Most speakers of North American English spell the word without the acute accent and pronounce it as one syllable: /ˈkuːp/ KOOP. This change occurred gradually and before World War II. A North American example of usage is the hot rodders' term Deuce Coupe (DEWS KOOP) used to refer to a 1932 Ford; this pronunciation is used in the Beach Boys' 1963 hit song, "Little Deuce Coupe".
The word "coupe" means "cup" in French, as in the rally competition Coupe des Alpes, and is for instance used for the Delahaye Coupe des Alpes (built 1935-1954).
Chevrolet, in an effort to lend a touch of class to its two-door hardtops during the 1950s, 1960s, and early 1970s, marketed them with the "Sport Coupé" moniker, using the original French pronunciation.
