八岐大蛇

Orthographic borrowing from Japanese 八(や)岐(またの)大(お)蛇(ろち) (Yamata no Orochi).

“cheater”

From a Japanese tweet which later become copypasta on Chinese social media, written in response to online allegations of infidelity against voice actress Amane Shindo. In the post, an angry fan created a pun from 二股(ふたまた) (futamata, “two-timing”), predicting that the 21-year-old would progress to 八股(やまた) (yamata, “eight-timing”) by age 84 and become a 八岐大蛇(やまたのおろち) (Yamata no Orochi) then.
