A sad creature whose sole reason to exist is to bombard others with SMS'.
These people has no social network except their SMS "friends", and will never actually answer the phone if you try to call them, but wait five minutes, then resume their messaging.
Not necessarily gender specific.

SMS-lish

A vernacular approach to communicating via SMS whereby one, either for the sake of supporting one's image as a hipster or frankly out of shear hubris, employs ridiculous--borderline incomprehensible--spelling shortcuts.

Girl: "Would you please text the neighbor to check on the dog?!"

Boy: "Forget that: she never writes back, and when she does, her SMS-lish drives me crazy."
