Textecho 

a conversion in which you spend all day describing what you are doing and when the conversion ends with the person you have been texting all day and a short while later they text to see what you are doing.

"This girl is so weird i spend all day texting her and she just sent me a textecho!"

textochondria 

The sudden feeling of having received an SMS/MMS text message despite the fact that you are not carrying a mobile phone. May be accompanied by a certainty of "hearing" your message tone and/or "feeling" your phone vibrate. Usually followed by confused searching of your pockets.

"Im sure i just heard my text tone"
"Dude, you left your phone in the car"
"Damn textochondria!"

Text echo

A text, that the longer it goes unanswered, the louder it rings in awkwardness.

'So how about that massage?? ;)' text echoed for a week.

text echo

the arrival of a text message as one is simultaneously calling the recipient

Fred had the burning desire to call Marge. He texted her, then seconds later, called her. As she answered the phone, the text message from Fred arrived. "Is this a 'text echo'?" she asked.
