Etymology
The word 'gangbuster' is a distinctly American English compound, emerging in the early 20th century during a period of intense focus on organized crime. It literally combines 'gang', a word which evolved from a neutral term for a 'journey' or 'group' to specifically denote a criminal band, with the informal agent noun 'buster', meaning 'one who breaks apart'. The term gained widespread popularity from the radio program "Gang Busters" (1935-1957), which dramatized FBI cases. Its figurative adjectival use, meaning "with great energy and success," logically extends from the image of such law enforcement efforts being vigorous and highly effective.
