니애미

Univerbation of 니 (ni, “you, your”) +‎ 애미 (aemi, alternative spelling of 에미 (emi, disparaging term for "mother")), originating from an implication that the addressee is engaging in incest (Cho Hang-beom 2019, pp. 372—378). Compare English motherfucker, Chinese 你媽的／你妈的 (nǐmāde).

First attested as 네 어미 (ne eomi) in Blood Rain (血의 淚/혈의 누), 1906, presumably because prudishness prevented it from appearing in writing earlier; the source in question was the first modern-style novel in Korean.
