textersonator 

A person who pretends they are someone else via text message. For instance: Picking up your boyfriend's cell phone and texting someone from his phone, as if you ARE the boyfriend.

Responding to a text message that wasn't meant for you as if you are the person it was meant for.

I thought I was texting Jim last night, but I found out it was actually Sally. What a textersonator, I'll never trust her again.

Textersonating 

Sucessfully impersonates someone while text messaging. Done by texting something that the person might say in a given situation.

Used to mock or put down.

John's text: Stop textersonating my mom.

Bill's text: John's mom: Oh Bill U R just mad
BC Bill is gonna B your new daddy.

John's text: U R such a dick

texterminator 

The person who unexpectedly ends a text chat without explanation. Leaving the other to wonder why?

Much like walking off in the middle of a conversation

I hate that she is frequently a texterminator, particularly when I'm not finished chatting. It's like her brain just shuts off.
