Anime:A term used to describe animation made by the Japanese. Anime is very much influenced by Disney, and Disney is now influenced by anime ^_^ Anime is most often noted for its big eyes, and exagerated anatomy (be it shoujo or shonen types). Despite some people thinking anime is just some rip off cartoons or porn (thats what my mom thought at first ^~^), some anime stories are very dramatic and have serious story lines, like Cowboy Bebop or Neon Genesis Evangelion . Other anime shows, such as Ninja Scroll are directed towards adults, with some things you wouldn't see on Saturday morning cartoon shows.
Bishonen/Bishoujo:Japanese for pretty(bi) boy (shonen) or girl (shoujo). Used to describe someone who is good looking, or in some cases, a male who has very femine aspects.
Chibi:Chibi in Japanese literally is a derogitory term for a child, but in anime, it means a small charater. Chibi charaters are often big eyed, with exagerated features (big face, etc). The most known chibi character is Chibi Chibi from Sailor Moon. Characters also sometimes go chibi, otherwise known as Super Deformed.
Doujinshi:Doujinshi is the Japanese term for a fan manga. There are many types of doujin (slang term), so if you type in "doujinshi" in a search engine, you can get anything from hentai to serious stories. Doujinshis can be good if used nicely, such as to enhance a certain part of a manga series already created, or create a new "episode" of the series. Other types of doujins can be gag series, which are mostly short stories (like a comic strip) of comedy. Be wary while searching for doujins, and make sure to read the descriptions carefully if buying.
Fan Service:Fan service is when there is mild nudity or suggestive content in a series to keep the males happy, yet not offend females. This could include series such as Video Girl Ai, or even Neon Genesis Evangelion when Shinji "trips" on Rei. Series such as Sailor Moon, DBZ and many other famous ones contain fan service, which is why there are censorship issues with Toonami. I personally find no problem with fan service, but some people may be offended (ie "how convienent, Chun Li is taking a shower during the middle of the Street Fighter movie >:P").
Hentai:Hentai is basically anime/manga porn. It usually features exagerated sexual body parts. Some people think that all anime is hentai, which is not the case. Hentai series are usually doujinshis or adult series. Hentai in Japanese means "pervert", so if you hear a character call another one that, they don't mean the actual hentai :P
Kawaii:Japanese for "cute", often referring to super deformed anime, or a chibi character.
Lolita:Lolita is a term used for hentai (porn) involving little children (girls mostly). Lolita comes from the book Lolita in which a 40 some year old man falls in love with a 14 year old girl. Lolita hentai is popular among men in Japan, and is usually from doujinshi. Young girls are attractive in the Japanese society, especially the sailor fuku (school uniforms).
Manga:As anime is to video, manga is to book. Manga is the book form of Japanese art. Manga is similar to anime, yet there are benefits and downsides to having only both. Manga allows more description in each shot, yet it is sometimes harder to portray an action sequence, or a drastic change with only manga panels. In some cases, manga goes farther in depth with the series, while anime episodes my break down a manga book in order to make the episode.
Manga-ka:Japanese term for a manga artist. Manga-ka is a hard job, but it is a very respected and desired job there, unlike comic artists here in the States.
Omake:Omake means "extra" in Japanese. Omake are sometimes featured at the end of an anime series, or in the end of a manga. They can feature silly stories, to author notes, to alternative scenes (like in the first volume of Fushigi Yugi). Most CLAMP manga have a little author(s) note at the end, with cute little CLAMPerettes. ^_^
Otaku:Otaku is a controversial term used to describe a very esentric anime fan. It first derived from a psycho guy who watched too much Lolita Hentai. He ended up kidnapping, killing and raping little girls. He called himself an "otaku", which was considered very vulgar until recently. the original story behind otaku is what sometimes gives people the wrong impression about anime, leaning towards the more violent series like Akira. Other people claim that otaku has no Japanese meaning, other than a house :P Its all a matter of opinion, and if you choose to use this saying, make sure you know who you're talking to so they don't take offense ^_^
Seme:A yaoi term, used to describe the more dominient or aggressive sexual partner (the "top" one).
Shonen Ai:Shonen ai ("boy love") is manga/anime that features a male-male romance. In most cases, the characters are feminine looking (or atleast the passive one). Shonen ai and Yaoi are (for some people) interchangeable words. Others may disagree, saying yaoi is the actual sexual part, while shonen ai is just a romance.
Shonen Manga:Shonen manga (shonen is Japanese for "boy")is manga that is directed to/made for boys, but everyone can like them. They usually feature a brawny hero who fights bad guys. Most of this type of manga is action and adventure, with perhaps a bit of romance on the side. Shonen manga usually features men with lots of muscles, spiked out hair (DBZ is an example), and mainly brute strength.
Shoujo Manga:Shoujo manga (shoujo means "girl" in Japanese)are usually series aimed towards small girls or teenage girls, however shoujo mangas are for everyone (yes this means you guys!!). Most shoujo manga revolves around romance themes, or using magical tools to save the world and such (Card Captor Sakura is an example). Shoujo manga usually focuses on girls, or feminine looking boys (most CLAMP things have very feminine boys like Kamui or Yuki). The figures are usually long hair, really big eyes, with long and slender bodies (arms, legs, hands, etc).
Super Deformed:Super Deformed (S.D.) is a term people use to describe when an anime character goes chibi, or little. Most of the time, charaters do this in a funny moment, to add a comic relief to the situation. In omake series (like what CLAMP has at the end of their manga, or in Blue Seed), characters are added as S.D. Sometimes, characters can gain cat features (like in Rayearth, or Peach Girl) to show slyness, or just to be cute. ^_^
Uke:A yaoi term used to describe the more passive and gentle of the two partners ("bottom" one).
Yaoi:Yaoi is male-male relationships in manga. As mentioned earlier in Shonen Ai, there are different views of if they are interchangeable. Yaoi is usually doujinshi of favorite characters (Gundam Wing is a yaoi favorite, seeing as it has 5 guys :P), but there are Manga-Ka out there who draw yaoi (most yaoi artists are female).
Yuri:Yuri is the female equivalent of Yaoi (girl-girl romance). Yuri usually isn't as common as yaoi.
