For those wondering, "Stanning" is a portmanteau of the words "Stalker" and "Fan", meaning overly obessed fandom of some celebrity.

That actually sounds much more logical of an explanation than the link to the Eminem song. I discovered the term back in the Tumblr days of 2013 or so and was surprised to hear it was related to a then 13-year old song.
