What is a chubby chaser? It is some who has a preference for large cuddly people. And in this day and age, that is a large demographic. If you are a chubby chaser you may as well be proud of it and wear your heart on your sleeve...or your chest in the case of a t-shirt. Possibly your head if it's a cap. Hey, if it's a sticker or button you can wear it just about anywhere.
