Also known as S1FMR, it is a phrase coined by far-right TikTok personality Postman, in response to a video made by leftist Jewish TikTok user MonicaLeJewski, who suggested that Postman probably says "Score One for the Master Race" to himself in the mirror. The term is often associated with racist and white supremacist rhetoric, signaling a covert endorsement of white nationalist ideologies without explicitly stating them.
