On the word "stan" and its use:
Before this message board began using the term left and right, I always found that people used it with a hint of irony. People would use it in reference to themselves, but there was a slight tongue-in-cheek exaggeration to the way it was used.
Also, while it's definitely valid to use it as a noun to describe a person, most of the uses I've seen of it outside this board were as a verb. As in "I stan [actor name]." And usually when people said that, they just meant they follow their work very closely. As in, you were "stalking" their career, not the person themself.
Of course, the lines become blurry with live theatre, because the actor is physically there, so in order to "stan" someone's career, you DO have to physically go where the actor is. Also, I'm not saying that many young fans aren't guilty of stalker-ish behavior. But I always find it a little funny when people sincerely use the term "stan" in association with that behavior, when I've always viewed it as a kind of jokey, ironic term.
Some people definitely do use the term to pejoratively or judgmentally - it's not just people on this board. But I think it's interesting to examine how different group use it in different contexts, and how the medium of live theatre sort of imbues the term with new meaning. Because if someone says they "stan" Jennifer Lawrence, they probably just mean that they watch all her movies and maybe her interviews too, which is fairly harmless. But when there are real-world interactions going on, it may be easier for lines to be crossed.
