Plural of bundock; also a variant spelling or reference to remote, rural, or undeveloped areas (variant of 'boondocks').
From Tagalog 'bundok' (mountain) through American military slang in the Philippines around 1900, eventually generalized to mean remote rural areas.
This word came straight from American soldiers in the Philippines who heard the Tagalog word for 'mountain' and turned it into 'boondocks'—military slang that changed English forever!
