We all have our favorite celebrities, but sometimes, fans can go to the extreme level with their unhealthy obsessions.
Being excessively addicted or obsessed to a celebrity is actually a disorder called ''Celebrity worship syndrome, CWS'' which is when a certain fan starts a psychological relationship with performers and celebrities, the CWS is a type of par-asocial relationship that occurs when a person has an obsessive fascination towards a certain celebrity.
CWS was expertly depicted in Eminem’s song Stan which broke the internet, soon after, a new term has come to light; Stan- (stalker+fan = Stan).
Since Eminem's hit song was released, Stan tells the story of an overly dedicated fan who turn out to be a stalker, and ever since, Stan became a term when referring to an obsessive fan.
And some celebrities were unlucky as they have lost their lives, brutally by the hands of their fans.
