Manatsu no Yo no Inmu (真夏の夜の淫夢, lit. "A Midnight Summer's Lewd Dream"), or Inmu (淫夢) for short, is a series of memes that spawned from Japanese gay porn videos. The titular video was released in 2001 by Coat Corporation, but the term has expanded to include other works by other companies like Acceed, Samson Video, etc.
It's often paired with Gachimuchi (Wrestling Series) and Kuso Miso Technique (Yaranaika) as the "Holy Homo Trinity" (御三ゲイ) since all three were well-known homoerotic memes that were popular within Japanese communities in the 2000s. However, when Niconico emerged in the late 2000s, it was considered an arch-enemy of Gachimuchi and fans would often flame each other's videos.
While Gachimuchi would become popular internationally and more recognized after several Gachi MADs were uploaded (and re-uploaded) on YouTube, it would later be supplanted by Inmu on Nico Nico Douga and within the Japanese community after more videos of Yajuu Senpai were uncovered around the 2010s.
Inmu is often linked with the Cookie☆ series of Touhou memes, after they latched onto the original video that started the meme (even coining the name it now uses), and the developments thereafter relating to said video.
