Leet (or "1337"), also known as eleet or leetspeak, or simply hacker speech, is a system of modified spellings used primarily on the Internet.
The term "leet" is derived from the word elite, used as an adjective to describe skill or accomplishment, especially in the fields of online gaming and computer hacking.
The Cult of the Dead Cow hacker collective has been credited with the original coining of the term, in their text-files of that era.
[3] One theory is that it was developed to defeat text filters created by BBS or Internet Relay Chat system operators for message boards to discourage the discussion of forbidden topics, like cracking and hacking.
More obscure forms of leet, involving the use of symbol combinations and almost no letters or numbers, continue to be used for its original purpose of obfuscated communication.
These are euphemisms that aim to evade automated online moderation techniques, especially those that are considered unfair or hindering free speech.
The approach has gained more popularity in 2023 and 2024 due to the rise in conflict between Israel and Gaza with the topic's contentious nature on the Internet, especially on Meta and TikTok platforms.
[13][14] For more casual use of leet, the primary strategy is to use quasi-homoglyphs, symbols that closely resemble (to varying degrees) the letters for which they stand.
[1] Limitations imposed by websites on password length (usually no more than 36) and the characters permitted (e.g. alphanumeric and symbols)[15] require less extensive forms when used in this application.
Leet can be pronounced as a single syllable, /ˈliːt/, rhyming with eat, by way of apheresis of the initial vowel of "elite".
Leet has its own colloquialisms, many of which originated as jokes based on common typing errors, habits of new computer users, or knowledge of cyberculture and history.
As the leet cipher is highly dynamic, there is a wider possibility for multiple users to share the "same" name, through combinations of spelling and transliterations.
used in multi-user environments such as multiplayer video games and instant messaging; it, like haxor, is one of the early leet words to use the -xor suffix.
Owned and pwned (generally pronounced "poned"[27] [pʰo͡ʊnd]) both refer to the domination of a player in a video game or argument (rather than just a win), or the successful hacking of a website or computer.
As is a common characteristic of leet, the terms have also been adapted into noun and adjective forms,[24] ownage and pwnage, which can refer to the situation of pwning or to the superiority of its subject (e.g., "He is a very good player.
It implies domination or humiliation of a rival,[32] used primarily in the Internet-based video game culture to taunt an opponent who has just been soundly defeated (e.g., "You just got pwned!").
It is sometimes used in legitimate communications (such as email discussion groups, Usenet, chat rooms, and Internet web pages) to circumvent language and content filters, which may reject messages as offensive or spam.
The word also helps prevent search engines from associating commercial sites with pornography, which might result in unwelcome traffic.
Conversely, in the RPG Kingdom of Loathing, prawn, referring to a kind of crustacean, is spelled pr0n, leading to the creation of food items such as "pr0n chow mein".
