Buttfluencer
A combination of butt and influencer.
A person (usually a girl) who posts fitness related content on social media, primarily Instagram, pertaining to be an influencer, but where the picture or video on their post is mostly about their butt in tight fitting clothing. Often tries to demonstrate how to do an exercise, but the emphasis of the visual materials is more on their butt and less on the exercise itself, often to the detriment of what they're trying to demonstrate.
