So in kpop calling yourself a fan or stan is everyday and thought as positive. But in other hand I have seen people calling out term "stan" saying that it comes from Eminem's song Stan and means stalker fan. However if we think of term fan it's also short from fanatic so neither of the words have positive initial meaning. To me both of the terms have been flipped around by the fandoms and reclaimed. Even more than terms of like geek, nerd or weaboo/weeb have. So to me pointing that stan comes from Eminem's song about stalker fan is pointless cause that's not what it means to people anymore. Rather I take "i stan *insert group" as "i stand for *insert group*" cause that's way more close what people mean by that . Even if word had a one meaning in the past doesn't mean that it currently has that meaning
