Extended Knowledge
Leet Speak originated in 1980s BBS (Bulletin Board System) communities, initially used to bypass content filters. As internet culture evolved, 1337 Speak became an iconic language of hacker and gaming culture. The name "1337" comes from the Leet spelling of "LEET", which is short for "Elite". Modern Leet Speak has evolved from a practical tool into a symbol of internet subculture.
