This clip is associated with Gabriel, a major character from the 2020 indie shooter ULTRAKILL. Short Gabriel voice lines became popular in gaming circles because they are dramatic, easy to recognize, and fit fast edits. “Enough” spread through meme compilations, reaction posts, and game soundboards as a clean interruption sound. Its staying power comes from how quickly it communicates anger, authority, and finality without needing any setup, much like other hard-stop game and meme reaction sounds such as nope.
