An addiction to any activity on the internet, games, social media sites ie: Facebook, Twitter, Pinterest,Instagram etc.
the obsessive compulsion to go online and participate in any of the above.
I started reading my email this morning but got sucked into Pinterest for two hours, and after 100 pins I was so close to a thousand I had to keep pinning! It's worse then my compulsion to check My Facebook page every hour. It's another cyber-diction.
