The Big Three (御三家)[edit source]
The three major genres (三大ジャンル San dai janru) are a generic names of the genres Touhou Project, The Idolmaster, and VOCALOID. These genres are identified by this name due to their steady popularity with Niconico users.
- Touhou Project (東方Project Touhou Project) is a Japanese doujin game series that specialises in shoot 'em ups by sole Team Shanghai Alice member ZUN. Generally, it's a series of 2D (with 3D background) vertically-scrolling danmaku shooting games, that also creates related print works and music CDs. Touhou Characters are often mixed into some Gachimuchi videos because Touhou music is one of, if not is, the most popular genre used in Gachimuchi. Usually the Character's heads or hair are pasted onto the footage of the wrestlers.
- The tag used for Touhou Project × Gachimuchi Pants Wrestling videos on Niconico is 東方餡掛炒飯 (Touhou Thick and Saucy Fried Rice).
- The Idolmaster (アイドルマスター Aidorumasutaa, officially stylized as THE iDOLM@STER) is a Japanese media franchise that began with a raising simulation and rhythm video game series created by Bandai Namco Entertainment (formerly Namco).
- The tag used for The Idolmaster x Gachimuchi Pants Wrestling videos on Niconico is ガチムチM@Ster (THE GACHIMUCHIM@STER).
- VOCALOID (ボーカロイド Boukaroido), and its succeeding versions are voice synthesizing applications that have been sold commercially since 2004. VOCALOID2 would be the one to introduce Hatsune Miku, which, by the time that the first video of Workout: Muscle Fantasies 3 was uploaded to Nico Nico Douga in August 10, 2007, was beginning to become extremely popular in Japan and other foreign countries. Billy Herrington would often be seen with Hatsune Miku because of her coincidental release date as the copy of Workout: Muscle Fantasies 3 was uploaded around the same time period.
- The tag used for VOCALOID x Gachimuchi Pants Wrestling on Niconico is 歪音エナ (Yugamine-ENA).
