look up any word, like the eiffel tower:
n. The combination of the words 'text' and 'retard'. Used to describe someone that will constantly use text-speak nearly to the point of you wanting to slap them several times for looking so unintelligent and all-around annoying. However, using frequent text language, with the acception of cell phones and actual text usage, does not make one a textard. To be a textard, they must use text-speak constantly for virtually every word in the sentence when it's unnecessary.

or text-tard, or texting retard, someone who has trouble sending text messages from a cell phone key pad (makes many mistakes, takes a long time to send a message or a reply) or someone who sends a text message (usually personal and not to be disclosed) to the wrong person.
Joe is such a textard, every time i text him, he takes forever to send a reply.

Jill had a textard moment when she sent a picture of her bare ass to her dad instead of her boyfriend.
