f3lip40 Mug

f3l1p40 or F3L1P40 are some written examples of leet forms for the name Felipão. Leet (written 31337, 1337, L337, 13370rz, and l33t), or Leetspeak, used primarily on the Internet, uses various combinations of ASCII characters to replace Latinate letters. The term is derived from the word "elite", and the usage it describes is a specialized form of symbolic writing. Different dialects of leet are found on different online forums. Initially, the word leet was used as an adjective, to primarily describe the behavior or accomplishments of others in the community. In that usage, Leet generally carries the same meaning when referring to either the game prowess or, in original usage, hacking expertise of another person. From adjective form its use then expanded to include use as an expletive or interjection in reaction to a demonstration of the former qualities. With the mass proliferation of Internet use in the 1990s into the 21st century, Leet has since become a part of Internet culture and slang. Leet may also be considered a substitution cipher, albeit with much variation from user to user. Leet originated within bulletin board systems in the 1980s, where having "elite" status on a BBS allowed a user access to file folders, games, and special chat rooms, often including archives of pirated software, pornography, or text files documenting topics such as how to construct explosives and manufacture illegal drugs. 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. However, creative misspellings and ASCII-art-derived words were also a way to attempt to indicate one was knowledgeable about the culture of computer users. Once reserved to use by hackers, crackers, and script kiddies, Leet has since entered the mainstream. It is now also used to mock newbies, or newcomers, on web sites, or in gaming communities. Some consider emoticons and ASCII art, like smiley faces, to be Leet, while others maintain that Leet consists of only symbolic word encryption. 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 encrypted communication. It is also sometimes used as a script language.
