Ah, Jen Selter. Internet goddess. "The Best Butt on Instagram." We've featured her more than a few times on Hump Day, she's been Babe of the Day -- girl's a Web superstar, all thanks to those glorious glutes. But (heh) pictures of her rear only tell one part of the story. Seeing that booty in action is what you really want to get behind. (Sorry 'bout that last one.)
