New internet challenge involves putting phones at risk
Phone pinching involves pinching the edge of your phone between your thumb and forefinger before dangling it over somewhere that it could be badly damaged or lost if your grip slips, hence the extreme part of the challenge.
The Mirror is crediting, or blaming, indie pop band Twenty One Pilots with kickstarting the craze. If you want to follow the latest submissions, search for the hashtag #extremephonepinching.
