John Wick is the title character of the action film series that began in 2014, played by Keanu Reeves as a retired hitman drawn back into violence. The films built a reputation for stylised gunfights and an almost mythic hero, which made the name itself shorthand for someone dangerous and impossible to stop. Online, the drawn-out pronunciation turned into a meme sound, shared in edits and reaction videos whenever an ordinary person or animal suddenly seems far more formidable than expected. Its brevity and instant recognition keep it useful for quick jokes and dramatic entrances.
