This sound is associated with Flappy Bird, the mobile game created by Dong Nguyen and released in 2013. The game became a massive viral hit because of its simple one-tap controls and punishing difficulty, and its sound effects became part of that identity. Online, the wing flap is still used in gaming edits, short memes, and nostalgic mobile game compilations. Its appeal comes from how quickly it evokes endless retries, tight timing, and the familiar rhythm of tapping through pipes.
