Textheimers 

The act of sending a Text message to someone and not receiving a reply immediately, whereupon the recipient replies, and you have no idea what they are talking about

JON: Hey, do you want to go out tonight?

An hour later...

LISA: Sure! where did you have in mind?
JON: What? What are you talking about?
LISA: You asked if I wanted to go out tonight.
JON: Oh! sorry, I had Textheimers.

Textheimer 

Sending a text that auto corrects your words and makes you sound like you've losing your mind.

"I'm worried about Phil, all his messages are textheimer's"
