Interesting bit of trivia...

From the truly-not-important-but-fun-to-bring-up-at-dinner parties file (I know, you're asking what sort of dinner parties do I go to):

"Boondock" is derived from the Tagalog word "bundok" which means "mountain". The word came into American use after the Filipino-American War (which followed the Spanish-American War) when returning military personnel used the term.
