The sound comes from the French dub of StarCraft 2, Blizzard's 2010 strategy game, where the Protoss Dark Templar answers commands with a grave 'oui'. French streamer Zerator reused the line on his ZeratorTV channel as the alert for viewer subscriptions, which is how the short clip spread beyond the game itself. Shared between fans as 'oui zera', it became a recognisable in-joke in French streaming circles and is now posted as a standalone reaction sound, separate from any gameplay, whenever a blunt but theatrical yes is needed.

The Oui sound is the French Dark Templar voice line from StarCraft 2, used as Zerator's subscription alert and as a short yes reaction in streams.
This clip is a single drawn-out 'oui' spoken in a deep, distorted voice by the Dark Templar unit in the French version of StarCraft 2. The line lasts just over two seconds, with a low, echoing delivery that makes a simple yes sound strangely solemn and funny at the same time. Because it turns agreement into a dramatic announcement, viewers instantly recognise it as an inside joke linked to Zerator's channel, where it plays for new subscriptions and now works as a quick, deadpan reaction to anything that deserves an exaggerated yes.
