Leetard
A person who always uses "leet speak" in their writing not because they think it makes them look cool but rather because it's the only way they know how to communicate.  Lacking the most basic knowledge of Elementary school English they apparently learned this strange sort of strange phonetic based pseudo-language entirely from each other instead to make up for having so much as a 3rd grade education.

"h0w r u doin 2day m8?"

"I was fine until some leetard sent me a text message that reminded me of the appalling state of our failing education system."

"lolwut?"
