A pimpster is a combination of the words "pimp" and "hipster." It is used to describe a hipster who also happens to be a ladies man. The typical pimpster can be spotted on most college campuses, attracting the opposite sex with his American Apparel attire and "noncomformist" attitude.
Stu is such a pimpster, he had sex with three girls at the same time the other night and did not even bother to take off his thermochromatic sweatshop-free t-shirt, or his socks for that matter. His facial hair is so sexy.
