Jean Onche is a long-running troll persona from the French jeuxvideo.com 18-25 forum, later associated with Onche.org, where he appears as an aggressive, foul-mouthed prankster archetype. This particular 'dégage' shout circulates in French gaming culture, credited here to the Baylife GTA roleplay community, and gets reused in Garry's Mod troll compilations and French meme soundboards. Like other loud command clips such as FBI open UP and the dismissive nope, it works because a single shouted word needs no translation, which is why short rejection sounds keep spreading across reaction memes.
