Belfie

Belfie (transl. butt selfie) is a self-portrait photograph or a short video of one's own Buttocks, a portmanteau of "butt" and "selfie," popularized around 2014 by fitness enthusiasts and celebrities like Jen Selter, Kim Kardashian. The trend led to the invention of the "Belfie Stick," a bendable selfie stick designed to help people capture these rear-end photos from behind.
