The sound comes from Félix Lengyel, better known as xQc, a Canadian former professional Overwatch player who became one of the biggest streamers on Twitch. Clips of his loud, reactive outbursts have circulated on Twitch, YouTube and social media for years, with desk slamming becoming one of his most recognised running behaviours. Short excerpts are regularly reposted as standalone reaction sounds separate from the original stream. That separation is why the clip endures, because the banging and shouting communicate pure frustration even to viewers who never saw the game that caused it.
