Navy Seal Copypasta, also called the Marine Copypasta, Internet Tough Guy Copypasta, and Gorilla Warfare Copypasta, is a facetious wall of text written to look like a genuine threat from an unhinged combat veteran3. The classic version opens with 'What the fuck did you just fucking say about me, you little bitch' and escalates into boasts about being the 'top sniper in the entire US armed forces,' racking up '300 confirmed kills,' and holding a degree in 'gorilla warfare,' a deliberate typo of guerrilla warfare that became the meme's most quoted line5.

The joke sits in the gap between the writer's grandiose claims and the trivial insult that supposedly set them off. Copy-and-paste variants stripped the original context so anyone could drop the block of text into a comment section as a mock response to a mild disagreement1. The comic typos, the 'over 700 ways with just my bare hands' brag, and the promise of a strike so precise it 'wipes out the pathetic little thing you call your life' were widely quoted on their own long after the full rant faded from active use.

The typical use is to paste the full text as a reply to any minor slight or disagreement online, playing on the absurd escalation for laughs. Common variants swap the branch (Marine Copypasta), the training term (gorilla for guerrilla), the kill count, or the language, as Richi Phelps' Spanish version showed6. Truncated snippets like 'What the fuck did you just fucking say about me' often stand in for the whole rant in casual chat.
