メンヘラ

Japanese Slang Japanese ★★★ 3/5 very-casual メンヘラmenhera

読み メンヘラ

ローマ字 menhera

漢字の分解 From English 'mental health' abbreviated to メンヘル (menheru), with the suffix -ラ (-ra) as an agent noun marker, forming 'mental health person'

発音 /meɴ.he.ɾa/

意味

A label for someone perceived as emotionally unstable, overly needy, or having mental health issues — often used critically.

メンヘラ originated on the 2ch (now 5ch) mental health boards in the early 2000s, derived from 'mental health' → メンヘル (menheru) + the agent suffix -ラ (-ra) to mean 'mental health person.' Initially self-referential among board users, it spread to mainstream internet culture as a derogatory label for people — especially women — perceived as emotionally unstable, clingy, or manipulative. While some people reclaim it jokingly, it remains a potentially offensive term that trivialises genuine mental illness.
