A hardcore enthusiast of video games; a gamer.
The term was coined by non-gamers working in the localisation department of Nintendo's European headquarters in Frankfurt, Germany, and is an abbreviation of Nintendoid.
The word is used to describe people who display
characteristics including (but not restricted to) long hair, poor dress sense, a lack of
personal hygiene and social skills, and few interests beyond the world of video games,
science fiction and fantasy.
