A Japanese word describing a person beyond the realm of fandom but into mania that is improperly used by American fans.
In Japan the word "otaku" has become taboo because of Miyazaki Tsutomu who went on a toddler murdering spree in the 80's, video taping the young girls he had murdered from an obsession with lolicon (female pedophilic manga).
Americans use this term to call themselves "fanboys" or "fangirls" with almost no knowledge of the horrific roots behind the word.
American Fangirl: "I have a huge collection of Macross, NGE, Sailor Moon, yaoi, and many other anime! I'm such an otaku!"
Non-anime fan: "...Uhm, you do know about that word right?"
CANNOT BE SELF-PROCLAIMED! beware of people who brag about how much they smoke and think their "cool" status relies on how much they smoke a day. all depends on the mindset about smoking, just chilllllin.
poseur: "dude, i'm such a stoner."
stoner:"no, you're definitly a poseur."
