Origin of son of a gun?

Answer:
The earliest use of the phrase was when, during the 1800's, the British used this phrase for babies (maybe just boys, specifically) who were born at sea. This would occur when British sailors would take women along on their voyages.


"Son of a gun", as an expletive, doesn't make all that much sense with this information, since you'd never shout "IDIOT!" as an exclamation of emotion, but it seems to go well with how some people might say "why you son of a gun" or whatever.
