The Navy Seal Copypasta, also known as the 'Gorilla Warfare' rant, originated on 4chan around 2010. It depicts an aggressively over-the-top reaction from an anonymous user claiming to be a decorated US Navy SEAL with over 300 confirmed kills. The text is famous for its hilarious misspellings—most notably 'gorilla warfare' instead of 'guerrilla'—and its escalating threats of 'precision the likes of which has never been seen before.' It has since become the gold standard for parodying 'internet tough guys' who take online disagreements far too seriously, often being copy-pasted in its entirety to mock someone's unearned sense of authority or aggression.
