Generally females in the age group of 12-17 who participate in the social medium which is familiar to hipsters and food fanatics: Instagram. Instawhores compete against each other to take the most revealing photos of themselves. These photos are usually followed-up by numerous amounts of hashtags (such as '#Swag' and '#YOLO').
