Team Fortress 2 is Valve's class based multiplayer shooter first released in 2007 as part of The Orange Box, and its chunky comic style menus have a distinct set of interface sounds. The button release tick is part of that everyday UI language, heard constantly while browsing servers, loadouts and settings. As TF2 clips spread on YouTube and in Source Filmmaker edits, creators began lifting its menu sounds for other videos, much like other short click sounds used as instant feedback. Its brevity and familiarity keep it useful long after release.
