A rash that fans of the Kardashian fam jam receive once they become crazily obsessed. It usually appears on the belly and is very itchy. You should not scratch it and you should immediately seek medical help when diagnosed. One of the known home remedies for a Kardash Rash is Coca Cola. The good thing about a Kardash Rash is that you know you are a good fan.
Person 1: Hey, did you see Keeping Up With The Kardashians last night?
Person 2: Don't remind me, it brought back my Kardash Rash. *itches belly* Do you mind grabbing me a coca cola?
