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.
