yandere

What does "yandere" mean?
A "yandere" is a character archetype, typically found in anime and manga, who appears sweet, loving, and gentle on the surface but possesses a hidden, unstable, and often violent obsession with a romantic interest. The term is a portmanteau of the Japanese words "yanderu" (to be sick) and "deredere" (lovestruck/lovey-dovey). The mental image is someone who would do anything—including committing crimes—to protect or possess their partner. While the term originated in subculture, it is now widely used in casual conversation to describe anyone whose display of affection crosses the line into possessiveness or stalking behavior. It is almost exclusively used in informal contexts, often with a mix of humor and slight alarm.
