Where did the Boondock Saints get their name?

Answer 1

The "Boondock" part of their name comes from the fact that they lived and worked in the boondocks of Brooklyn. The word "boondock" generally refers to a remote, rural area; especially one with dense brush or jungle. It comes from the Tagalog word "bundock", which translates to "mountain", and was introduced introduced to the English language by U.S. soldiers operating in the Philippines. It's generally considered a slang word.

As for the "Saints" part, they were called saints because of their religious nature, and due to the fact that they only killed criminals. Thus, the Saints from the boondocks, or the Boondock Saints.
