An anti-goth, someone who is constantly happy, chirpy and smiling. They dress brightly, often with clashing colours and odd combinations to make themselves look even brighter. An example of a sunner is somebody who wears one red shoe with blue laces, one blue shoe with red laces, bright orange trousers/pants and a green shirt. Often they look like hippies, indies or a cross between the two but they almost always look oddly awesome and use their odd combinations to look even better. Most of them see almost everything as nice and wont take offence to insults.
Person 1: Why are you wearing such odd stuff, which looks strangely awesome?
Person 2: (in a happy voice) I have decided to reject dark things and become a sunner! :D
Person 1: Oh right... cool, I guess...
