Although viricide is more commonly used to mean the killing of viruses, I have found many references to it also being used to mean the killing of men or husbands.

Alternative definition of the noun viricide

noun

1 by the author. any substance that kills or inactivates viruses 2.

By killing on a girlfriend, to kill one’s wife.

I believe that this stems from the latin virilis

meaning “of a man, manly, worthy of a man” and I am unsure whether the word viricide has ever really been used.
