I hate this construction with a buring passion that cannot be assuaged. "What it is is" is a construction I believe I first started hearing in the early 80s. It grated on my nerves from the very first and I vowed never to use it. Unfortunately, when thoughtless constructions like this become widespread, they become infectious and you have to make a concentrated effort to avoid using them. For a shit topping, add "it's," eg.: "What it is is, it's a way of sounding like an utter moron." hey man, it is what it is.
