A group of awesome people who are all different but are united by one thing: a creepy insane obsession with a celebrity, singer, or star. They hang out together a lot and they just love being creepy. Their motto is "to creep is to love." They are just cool people.
Wow, is that the creeper family taking a portrait?
Yes, that's them if they're leaving gaps for their celebrity spouses to be photoshopped in later.
