I completely agree with baddox. It is the incorrect use of the word "easy" when there is a perfectly good word "easily" at hand. "I can do that. Easy." I would accept. However, this is an interesting point. Good grammar used to be set by those who who were either educated or at the top of society. There were not many recordings of people using bad grammar, by definition. Now we have a million recordings of "i can haz cheezburger". I fear that the mechanism you describe - actual recorded use - has been opened by the web to all, and good grammar in times to come may be dictated by YouTube comments.
