Bastion is a playable hero in Overwatch, Blizzard's team-based shooter, and one of its most recognisable characters because he speaks in beeps, chirps and other mechanical sounds instead of full sentences. Those sounds have become a shorthand for robots, confusion and playful curiosity in gaming videos, and short clips like this one are widely shared on soundboards for quick reuse. Because the audio is only a couple of seconds long, it works as a reaction sound as well as a character reference, which has helped it stay useful long after players first heard it in matches.
