Son-of-a-Bastard is the 21st Century term for an idiot born of a bastard father.

A polite way of calling someone a son of a bitch, but more harsh than son of a gun. Best used in mixed company where a real swear might not be appropriate.

Back in the 1800's when the "pirate ships" docked at bay the crew would fuck hookers in the gun deck and impregnating the hooker. So when the hooker gives birth to the baby the baby was referred to as a "son of a gun"

1. The son of a prostitute.
2. The son of an unmarried mother, a bastard
3. Somebody objectionable.

Unlike son of a bitch which is in reference to ones canine mother, son of a motherfucker is in reference to ones father that it is assumed was a motherfucker.

Can also be used as a curse when frustrated or infuriated by something.

Back in the early 1800s, the British did something called impressment. During the Napoleonic wars, the British considered any ship that traded with the French an enemy. They would steal the supplies and capture the crew. They impressed the crew into the navy for life. These guys would work as sailors for the rest of their lives and never step on dry land again. If they had a wife, the British would bring the wife aboard the ship. If the wife was pregnant, they would place her on the gun deck near the cannons. When she started having contractions, they would fire the cannons to make her push to have the baby. When the baby was born, it was called a son of a gun. This termis is very negative.

A modification of an old favourite with a replacement of the noun bitch with an apparently less offensive synonym, but think about it.. would you like to be the son of choir boy molesterer? Thought not! Also handy as your less likely to get pulled up for shouting this at the top of your voice!
