The term "변태" (pervert) refers to someone who exhibits sexual behavior that is considered abnormal or deviant from societal norms. This can include a wide range of activities or interests that may be viewed as inappropriate or excessive. The definition can vary significantly across different cultures and contexts. In psychology, the study of such behaviors often falls under the category of sexual deviance. This can encompass various paraphilias, which are conditions characterized by intense sexual interest in atypical objects, situations, or individuals. Understanding these behaviors requires a nuanced approach, considering both psychological and social factors.
