The 'Oh Yeah Yeah' meme originated from YouTuber MaximilianMus, who used a profile picture of JC Denton from the game Deus Ex and encouraged his massive fanbase to do the same. This sparked a massive YouTube 'raid' in early 2019, where thousands of users changed their avatars and spammed the lyrics 'Oh Yeah Yeah' from his original song in every comment section across the platform. The meme represents a specific era of internet subculture defined by collective action, irony, and the rise of comment-section dominance. Today, it remains a nostalgic symbol of YouTube’s chaotic community challenges and the power of influencer-led viral trends.
