Bastardized Vernacular

Okay, why in seven hells have I heard two commercials in the last half hour that have used the word "ginormous?" Is this now an acceptable word in common usage?? Don't get me wrong. I have no problem with using slang. I do it ad nauseum. But I know if I were to use a word like ginormous in a meeting at work, I would probably lose a million respect points among my co-workers and supervisors. Oh well. I suppose that word will soon be in the dictionary along with "wuzup" and "lol." So I'll just have to sit back and accept it...
