A reference to the Eminem song Stan. The song is about an overly obsessed fan (named Stan) who writes letters to eminem and ends up driving off a bridge with his pregnant wife, because Eminem didn't write him back.

The terms means a very very overzealous and obsessed fan of a celebrity/band/cast of a tvshow or movie.
Person 1: I just love Ariana Grande so much I would die for her I would track her every move if I could

Person 2: woah don't be such a stan

Based on the central character in the Eminem song of the same name, a "stan" is an overzealous maniacal fan for any celebrity or athlete.
A Typical Kobe Bryant Stan would say something like.
"Kobe Bryant scored 81 points last night. Kobe could beat God himself in a game of 1 on 1 hoops. To hell with Michael Jordan or Wilt Chamberlain, they arent on Kobe's level!"

Stan is a mix of stalker and fan. Its a crazy fan who basically worships a celebrity. The word was popularized by Eminem and now it is generally used as a verb.
"Demi Lovato is a true queen! We Stan!"
"We stan a good sister!"
"Yeah, he's a crazy stan, bro."

Stan means you look up to that person, you watch them or you truly love their content. It's another word for saying you idolize someone or something. You would say, "I stan _____" instead of I "I love that person"

A song by Eminem off of The Marshall Mathers LP about a man who loves Eminem and his music to the point of insanity. The fan, whose name is Stan, meets Eminem at a show and then begins to write him letters. The letters get progresivly stranger. After a long time with no responce from Eminem, Stan puts his girlfriend in the trunk of his car and drives to a bridge. Stan tells Eminem all about what and why he is doing this from a tape recorder in his car. Stan then drives the car over the bridge, presumably killing himself and his girlfriend who was pregnant with his kid. The song ends with Eminem writing a letter to Stan right after his death. But Eminem then realizes that the man he has heard about on the news who drove his car over a bridge is the guy who has been writing him letters. In other words if Eminem had wrote the letter a week earlier Stan would have remained alive. Famous because it used the baseline and vocals from Dido's famous song "Thank You". Very powerful song.
" Have you heard in the news they're blaming some crazy guy killing someone because he listened to and was influenced by that song Stan?

"Of course, they always do that"
Dear Stan, I meant to write you sooner but I just been busy...

Stan is a depressing song.

unlike what most k-pop fans think, stan is not just liking something. a stan is a psychotic fan who would do anything for the attention of their idol. (term originally by Eminem in his 2002 song Stan)
person 1: dude did you see how person 3 killed himself because X didn't respond to his letters?
person 2: what a fucking stan
