The character Noob Saibot was named after Tobias Boon (Noob Saibot spelled backwards), one of the creators of the game. Considered to be the most dificult character of the game, Noob Saibot would "cheat" to win. Some would say their defeat by Noob Saibot was luck, chance.
It was common to hear someone say "you got noobed" when they would unfairly lose or to be called a noob if the person won in a "cheating" or "lucky" fashion while playing in a video game arcade.
Person 1: Wow, that guy was lucky!
Person 2: Yeah, you got noobed!
Example 2 -
That guy definitely cheats to win. What a noob!
