stan

The term "stan" originates from a combination of "stalker" and "fan," popularized by Eminem's song of the same name. It refers to an overzealous, obsessive, or intensely devoted fan who supports a celebrity, artist, or public figure with extreme passion. While once carrying a slightly negative connotation of being an unhealthy or dangerous stalker, in modern internet slang, it is frequently used as a verb or noun to simply mean being a "huge fan" or "super supporter." It is common in social media contexts to express deep loyalty to a brand, person, or pop culture icon.
