Omake: Omake (御負け , usually written おまけ) means "extra" in Japanese.  Its primary meaning is general and widespread.  It is used as an anime and manga fandom term to mean "extra or bonus."  In the USA, the term is most often used in a narrow sense by anime fans to describe special features on DVD releases: deleted scenes, interviews with the actors, "the making of" documentary clips, outtakes, amusing bloopers, and so forth.  However, this use of the term actually predates the DVD medium by several years.  For at least the past 50 years in Japan, "omake" of small character figurines and toys have been giveaways that come with soft drinks and candy and sometimes the "omake" is more desired than the product being sold.

Meganekko: Meganekko (メガネっ娘 ) (メガネ, also めがね or 眼鏡, pronounced "megane" ("glasses") and "ko" for "child" (子) but using the kanji for "daughter" (娘)) is an anime and manga fandom character archetype.

Otaku: Otaku (おたく/オタク ) is a Japanese term for people with obsessive interests, commonly the anime and manga fandom.  Its contemporary usage originated with Akio Nakamori's 1983 essay in "Manga Burikko".  "Otaku" may be used as a pejorative; its negativity stems from the stereotypical view of otaku and the media's reporting on Tsutomu Miyazaki, "The Otaku Murderer", in 1989.  According to studies published in 2013, the term has become less negative, and an increasing number of people now self-identify as otaku.

Fan service: Fan service (ファンサービス , fan sābisu ) , fanservice, or service cut (サービスカット , sābisu katto ) , is material in a work of fiction or in a fictional series which is intentionally added to please the audience.  The term originated in Japanese, in the anime and manga fandom, but has been used in other languages and media.  It is about "servicing" the fan – giving the fans "exactly what they want."  Fan service usually refers to "gratuitous titillation", but can also refer to intertextual references to other series or story and visual elements that audiences tend to desire.

History of wikis: The history of wikis is generally dated from 1994, when Ward Cunningham gave the name "WikiWikiWeb" to the knowledge base, which ran on his company's website at c2.com, and the wiki software that powered it.  c2.com thus became the first true wiki, or a website with pages and links that can be easily edited via the browser, with a reliable version history for each page.  He chose "WikiWikiWeb" as the name based on his memories of the "Wiki Wiki Shuttle" at Honolulu International Airport, and because "wiki" is the Hawaiian word for "quick".
