Trophyification is a term used to describe the mental state in which a person idolizes someone or something to the point of entitlement (that often escalates to dangerous degrees) within different variations of human interaction. For example, an obsessive fan who thinks they're entitled to a relationship with their favorite celebrity, which leads to them showing off possessive, controlling and stalking behaviors. This can even be used to describe 'nice guy' behavior (a behavior where someone--usually a male--believes they're entitled to sex or a relationship for being a decent person).
I'm tired of all these sasaengs and the trophyification of K-Pop idols. They're just people.
