The art of balancing a pokeball (TM) on your head and taking a photograph from 5 feet (exactly) away with the torso of the subject (person whose picture will be taken) in the center of the photo shot. The term smoshing was coined after the hit comedy duo known as smosh (TM?) who had a passion for the Japanese cartoon known as pokemon.
This is what most people do when they smash. Happens a lot at Old Baby. It's perfectly harmless and has shown no signs of health concerns. Commonly associated with the act of schlop.
