Often, that means starting a sentence with it is or there is. A common form of this type of expletive is the weather it.

It's un-dadgum-believable that an expletive can interrupt a word like that.You can always take out an expletive without changing the basic meaning of a sentence, but expletives can provide nuance and emphasis that are hard to achieve any other way. I love you is nice to hear, but doesn't quite capture the connotation of It's you I love. The expletive makes all the difference. That's why my advice is to minimize them rather than eliminating them.
I mean, wow, right?
What I did there, at the beginning of the sentence, you see it.

While reading this I thought this: Most effing TV weather people, sometimes called "meteorologists", should be referred to as "Weather It". For example: "Get out our long-johns, dear. The Weather It says snow is predicted for tomorrow."
Many Australians have an "adjective infixation" when it comes to the "Great Australian Adjective." (One of my favorite examples is "Nineteen-bloody-eight!")
