The 'In G Major' meme originated in the late 2000s within the YouTube Poop (YTP) community, characterized by a specific audio filter that shifts pitch and adds a demonic, echoing resonance. Visually, it is often accompanied by inverted colors or high-contrast distortions, making even the most innocent childhood logos like THX or Nickelodeon look terrifying. It became a staple of 'screamer' culture and creepypasta-style edits, used to mock the perceived scariness of certain media or simply to create unsettling, surreal humor. Today, it remains a nostalgic symbol of the early YouTube era's experimental and chaotic editing style.
