When the human brain malfunctions and exports text that may be considered words, a Killy is being pulled. Killy refers to the master of misspelling Kill_Man1234. This term was introduced in the first half of 2008 to describe, not the fact of misspelling, but the situation in which the brains malfunction. Oxford Dictionary reported an increased use of this term and will most likely inherit the term into their 2009 version.
