Originally an insult in japanese meaning "someone who stays inside their house because they are a fucking loser".
In the magnificent country of eagles, mcdonalds and freedom (as they say), this word is used by their most hated spieces, the weaboo.
They are the same people that call themselves nerds because they think it makes them look like some kind of a cool guy/gal, but only with japanese cartoons that feature little girls with tits the size of a skyscrapper.
Poor guys, have to deal with these creatures...

An anime-addicted, lock-in introvert that calls itself an otaku to feel cool. Beware though, for if they start talking about their favorite lolis, you have 10 seconds before your soul is drained. 40% chance of being in high school and a 99.9% chance of having a body pillow with an unexplained, moist hole torn in the back of it.
"Dude, did you stay up all night watching anime?!"
"THE OTAKU NEVER SLEEPS!!!"

Someone who doesn’t shower and gives off a horrible smell

Someone who doesn’t put on deodorant
“Bro, I sat behind a dude in my last class that smelled like an otaku. It was the worst”

Please take a shower, or put on deodorant so you won’t smell like an otaku.
