"Stoked on their favorite pro's" = signed posters, asking for a picture, following them on FB/Instagram
There is nothing wrong with this.
Being obnoxious, on the other hand, is asking someone for a bunch of free shit for being their first "liker" on their photo, asking for a bunch of free shit in general, and saying that if they don't get a shout out, then such and such will happen or they will be bummed out/have a bad day of skiing.
You can't deny that shit like this is out there.
I understand that in today's world there is that technology curtain that allows kids like that to do these obnoxious things, but at the same time, it doesn't make it right/normal.
