I recall seeing reference to Potterheads. However, since non-fans are Muggles, then perhaps we are witches and wizards. Thus, the first Potterhead in a family is Muggle-born and their descendants are half-bloods. A Potterhead from a family of Potterheads is a pureblood. Need I say more?
It's potterhead.... There are extensions for example if آپ have read all the کتابیں and watched all the فلمیں you're a pure blood. Therefore those who have only watched the فلمیں یا only read the کتابیں are half bloods. Those who have never read the کتابیں یا watched the فلمیں are muggles. Those who have read all the کتابیں and watched all the فلمیں and hate on muggles are death eaters
