Well, let’s check the dictionary:
There are some pretty dry definitions out there to explain what the heck an idiom is. How about this one:

True. Very true. But a bit clinical.
Iddy, our host, defines an idiom like this:

Welcome to the wonderful world of Idioms:
There are thousands of idioms in the English language. Some sources claim as many as twenty-five thousand. Iddy has started counting them but he’s only up to 35 at the moment. He’ll get back to you when he’s counted them all. In about twenty years.
Idioms are not exclusive to the English language and enrich conversations around the world. In Hindi, you might say that you were so angry you excreted embers. In Turkey you may tell a repetitive and boring speaker to stop ironing your head. And in Yiddish, you might tell that same person, as they continued to annoy you, not to chop your tea kettle.
