hypertextia
A serious mental condition characterized by excessive text-messaging on one's smart-phone (and/or obsessively imploring others nearby to let him use their cell phones for continued/additional texting if his own phone's battery runs out of juice from the user's constant voluminous correspondence).
Don't knock hypertextia too hard --- st least the person is willing to openly interact with others like all get out, which is more than can be said of many anti-social/closed-mouthed people... better to communicate too much than not enough.
Hypertextia
An overwhelming desire to text someone.
My urge to text her is so much so that it cannot even wait until I receive a reply for my previous text. I cannot eat, sleep, or talk to someone else before texting her. I guess I am suffering from a condition called hypertextia.
