What are annoying words? When you hear them, you just want to grit your teeth! Some of these are what we call "crutch" or "filler" words; something to fill up space and time until we can get the next sentence ready. But a phrase like "it is what it is" doesn't really fall into that category. There's another group of words and phrases that start out as fresh and new, then are overused to the point of becoming tired clichés. How about "reinvent," "iconic" and "cutting edge?"
