Boonies, short for boondocks, usually refer to someplaceremote or rural . . . like where I grew up . . . waaaaaaaaaaay out in thesticks.
The origin of 'boondock' is simple and straightforward but interesting, nonetheless.
The word was adopted by American soldiers during theSpanish-American war. The soldiers weredeployed deep into the forests and mountains of the island . . . or the bundoks, as the indigenous folk would say. . . ambushing the enemy and fight small concentrated battles.
‘Bundok’ becameboondock and thus became a part of conventional vernacular.
