look up any word, like sex:
 
1.
instances in which individuals engage in relationship-like activities over vast distances through the medium of the phone, computer or other digital media, generally with individuals that have only met a few times.

The use of sexting and phone sex has vastly improved the longevity of many phonationships world-wide.
Hey, are you still having a phonationship with that dude you met in Cancun last year?
