flat phone freak
A socially inept person who does not know how to communicate verbally or in person but does all their talking through texting on his or her flat screen cell phone. Flat phone freaks tend to be cowards behind keyboards. They rely too much on auto correcting spellchecking software thus making them incompetent in grammar and spelling. Then again flat phone freaks are way too dependent on technology to do anything to survive let alone write in cursive.
Look at those flat phone freaks text messaging each other while they are standing right in front of each other!
