Leet (written as 31337, 1337, and l33t), or Leetspeak, is a written form of slang (technically an argot) used primarily on the Internet, but becoming increasingly common in many online video games,[1] which uses various combinations of alphanumerics to replace proper letters. The term itself is a degenerative form of the word "elite", and the language it describes resembles a highly specialized form of electronic shorthand.
