BlackBerry neck

The distinctive pattern of unsightly creases and wrinkles caused by spending hours with a bent neck, looking down at one’s smartphone.

Historical perspective: Ryan Seacrest was terrified of contracting "BlackBerry neck," according to the National Enquirer in 2010. The American Idol host is on his BlackBerry all day, and a source says he keeps showing everybody his neck and asking if they can see anything. Now he’s trying to train himself to text without bending.
