Evidence suggests that both word and cooking technique migrated it's way from the Caribbean and into the languages and cultures of the Spanish, French and English via the usage of the word barbacoa, making its' way into the Oxford English Dictionary in 1697.
There are some historical etymological inaccuracies stating that it is derived from the French language. Urban etymology myth has it that visitors from France to the Caribbean saw a whole pig being cooked and described it as a barbe à queue, which translates to "from beard to tail". It is ambiguous as the French word for the same is also barbecue. There is another, slightly more obscure claim that the abbreviation BBQ came from the time roadhouses and bars with pool tables emerged in the USA, calling their enterprises "Bar, Beer and Cues". Apparently though, this was originally BBCue, which later evolved into BBQ.
