The line is attributed to Tomura Shigaraki, the decay-quirk villain at the center of Kohei Horikoshi's My Hero Academia, which began as a manga in 2014 and became a global anime from 2016. Short anime reaction clips like this travel fast: ripped from episodes, they get reposted across soundboards and edit pages until the original scene barely matters. The 'he cheated' delivery survives because it fits any accusation, gaming or otherwise, sitting comfortably beside other anime staples such as the Mangekyo Sharingan sound and the Re:Zero Return by Death clip.
