Japanese animation. The term applies to many different forms of Japanese animation, not just the kind with over-proportioned eyes and heads, exaggerated features, and revealing clothing.
This term sometimes refers to non-Japanese animation using similar styles.

Anime is NOT:
Japanese animated porn: See definition on hentai.
Only for nerds/geeks: Would you say all cartoons are for nerds/geeks?
Strongly masculine/feminine: Some are masculine, like Fullmetal Alchemist, and some are feminine, like Princess Ai.

A beast of a man who on the word practice humps any moving object in sight, esp. Fat Wielert and hot women. He sleeps in a cage and eats raw meat all day. He loves feeding women his monstrous elephant dong.

The Japanese term for animation. And just because something's animated doesn't mean it's automatically targeted at children so they can become corrupted by it. American companies usually butcher the dubbed version so they can make the ones that weren't intended for kids all TV-Y rated. Most anime takes on more mature themes and sometimes sexual content for those people who are into that.

Stereotypical anime characters, usually the younger female ones, have large eyes (to portray innocence, I guess). But not all of them do. Sometimes they have crazy hair and crazy outfits and crazy actions. The voices are high because I guess Japanese people tend to have higher voices than Americans.

The people who watch anime aren't always those stereotypical geek/nerd/dork or whatever you wanna call them. Sometimes the people who do watch anime or read manga (Jap. comics) can get a little too into the culture, but hey, whatever.

a disease that happens once a year to all anime fans when an anime convention appears.

symptoms:
It can cause dicoloration of the hair,skin, sometimes eyes. There is random cosplaying and seeing countless anime characters everywhere. Also people have been known to take pictures of you in your cosplay. The more extreme/amazing the cosplay the more pictures would be taken.
They hold an anime convention all over the world and held in certain towns to bring all the anime addicted fans in one place in hope of getting rid of their animeitis by letting them enjoy tons of anime for 3 whole days. It works for a little when they come back and they will not be as addicted or it could fail and make their disease worse by making them more addicted. There is no known cure for animeitis.
