Short menu-click sounds like this one became staples of online video once game capture and meme editing went mainstream, because every skit, quiz or fake interface needed a believable press. The 'M button' label suggests it was ripped from a user-made soundboard pack, where anonymous clicks are numbered rather than named, and re-uploaded many times. With only a handful of plays, it remains a niche pick, but that is exactly why editors grab it: a clean, unrecognised click that makes on-screen choices feel real without pulling attention.
