When you feel the need to forward a just received joke, picture or video to your friends (not to the sender, of course). To be unable to keep the received medium just for you.
Common similar activities called Obsessive Compulsive Disorders or OCDs include hand washing, counting of things, and checking to see if a door is locked.
This Christmas joke card is so great. It fits perfectly to John: Sent!

Oh dear, you suffer from CID, that social media disorder. The full technical term is Obsessive-Compulsive Instagram Disorder (OCID). Or just CID.
Oh, you are a wise guy.
