Garry's Mod, usually shortened to GMod, is a long-running sandbox game built on Valve's Source engine, and its menus are full of short, functional interface sounds. This clip is one of those list-selection sounds, the small click sound players hear when moving through items and options. As GMod gameplay, roleplay and meme edits spread on YouTube and TikTok, editors began lifting its familiar UI noises for videos far beyond the game itself. It remains popular because the brief pop sound is instantly readable as a choice being made, even for viewers who have never played GMod.
