The 'Bonk!' meme originates from the Scout class in Valve's legendary multiplayer shooter, Team Fortress 2. While 'Bonk! Atomic Punch' is actually an in-game energy drink that makes the Scout invulnerable, the term became synonymous with the satisfying sound effect of his wooden bat hitting an enemy's skull. Over the years, the community evolved the 'Bonk!' into a multipurpose reaction tool used to dismiss bad arguments, 'shut down' over-excited individuals, or most famously, to send people to 'horny jail.' Its enduring popularity stems from the Scout's arrogant, fast-talking personality and the universal comedic value of a well-placed, percussive sound effect.
