Scout is one of the nine playable classes in Valve's Team Fortress 2, a team-based shooter first released in 2007, and his fast, brash Boston persona helped make his lines and sound effects widely recognisable. Bonk became a familiar part of that identity, partly through Bonk! Atomic Punch, the energy drink Scout can use in the game. As TF2 clips, animations and fan edits circulated online, the short impact sound was lifted into soundboards and meme videos, where it now works independently of the original gameplay as a quick comic hit.
