On September 30th, 2007, a portion of a video titled "Professional-Pants Wrestling", originally named "Workout Muscular Men 3", was uploaded on the Japanese video-sharing website Nico Nico Douga. This clip and many others got very popular on the site, gaining various remixes and edited-videos that use those clips. These videos also contain various well-known characters, where the moans or voice lines they make are quite popular in the genre and in rips:
- Billy Herrington or Aniki (his porn star name)  (born July 14, 1969 - died March 2, 2018) - an actor in gay porn and an inspirational figure. In Gachimuchi videos, he would be the protagonist in most of them. In memes, his scream is one of the most used.
- Van Darkholme  (born October 24, 1972) - an American performance artist, director, and photographer of Vietnamese descent. Best known for his interview and the quotes he made in the film "Lords of the Lockerroom".

The first rip to feature Gachimuchi was "Ringside (Perfect Ver.) - Rhythm Heaven Fever" on the GiIvaSunner channel. The next rip using Gachimuchi was also the first use of it on the SiIvaGunner channel, "Main Theme - Metal Gear Solid 2: Sons of Liberty" rip. Many rips use sound clips from Gachimuchi videos to make YTPMVs, such as in the "Gerudo Town (Day) - The Legend of Zelda: Breath of the Wild" rip.
