We all know that we're a music-loving bunch in here. And it's fair to say that we have an ear for words.... especially odd words. So I wondered......
What words have you only heard in ONE song lyric? Some - ok, quite a lot - will be 'made up' words, but to me they stand out as unusual.
[This thread could quickly dry up if it's only ME that notices this
]One that might have been here is 'Hypotenuse' [which is not a Daily Prophet story about Harry and recreational drugs], but Giraffe helpfully showed me that James Blunt has added another song with this word in the lyric.
So here is a place where we can pose such words, have others identify where they came from with a nice rhyming couple of lines, and possibly prove each other wrong if we know other places that word appears.
To keep it friendly, how about we just use general knowledge of songs... if we search for things there's probably an obscure song that nobody knows that can be 'tracked down'.
I'll start off with:
Good-bye-ing [told you some were made up]
Where do I think it came from, and am I wrong about it being unique?
This isn't an "answer the line to post your own" - everyone join in with your unique words and we'll see how many we can identify
Should I have heard it? Is it one of those that I've been singing something else my entire life????
Beef or Pork? 
Never mind. At least I know some of the songs that the kids I teach are into.
