adj. a state of being, meaning to be in the Tetris zone. When playing a game of Tetris, if one has an exceptionally high score, you are said to be tetrilicious. To qualify as being tetrilicious, one must have a score of 250,000 points or higher. Anyone who declares to be tetrilicious but is under 250,000 points is a tetrilicious faker.
I just scored 872,000 points in Tetris! I am tetrilicious!!!
