The Internet slang term derived from “copy and paste” for a reposted block of text is “copypasta.” It usually means text copied and circulated online, often repeatedly and sometimes with the intention of amusing, provoking, or confusing readers who do not recognize it.
The term is a playful blend of the computing commands “copy” and “paste.” Its usage can be traced to an anonymous 4chan thread from 2006, while the word was also recorded that year in connection with Usenet and Urban Dictionary. A copypasta may be a rant, mock threat, catchphrase, paragraph, script, or formatted message.
Famous examples include the exaggerated “Navy Seal” copypasta, which pretends to be an intimidating military boast, and the “Bee Movie” copypasta, based on the screenplay of the 2007 animated film. The latter became especially popular through reposts on Reddit and Tumblr beginning in 2013.
Copypasta is broader than spam: spam is generally unsolicited or unwanted messaging, while a copypasta is defined by copied-and-reposted text and may be shared as a joke. It is also not automatically creepypasta, which specifically refers to horror-oriented Internet fiction or folklore.
