Leet is a phrase often used on the Internet, some being online games, message boards, and chat rooms. It comes from the word “elite”, meaning “above everyone else”. It’s most commonly written as “1337” or “l33t”. It can also be written differently, the numbers 1, 3 and 7 standing for L, E and T respectively.
