"Stan" is a term that originated from the song "Stan" by Eminem, which tells the story of an obsessed fan who takes his admiration to an extreme level. The word has since evolved to describe individuals who are overly enthusiastic or devoted to a particular celebrity, artist, or fictional character. A "fan" is someone who enjoys and supports a specific person, group, or activity, often participating in related communities or events. While most fans express their admiration in healthy ways, "stanning" can sometimes lead to toxic behavior, where the fan may harass others or become overly critical of those who do not share their enthusiasm.
