scratch
noun
a mark made by scratching:Her legs were covered in scratches and bruises after her walk through the forest.There was a scratch on the CD.Amazingly, he survived the accident without a scratch (= without suffering any injuries at all).
2[S] when people or animals scratch themselves:That dog is having a good scratch. It must have fleas.
(This is the official definition of the verb scratch, according to the Cambridge dictionary.)
My definition: A lot of trouble, especially if it appears on my back.
A scratch can be a “wonderful” reminder of a passionate night, but seen by someone who was not responsible for that scratch, it can also mean a lot of trouble, a very angry look, suspicious questioning and accusation of cheating.
I’ve have had re-appearing, mysterious scratches on my back for some time now. And trough all this time, I would not have a clue where they came from. Alien abduction? Raped by a beautiful woman while unconscious, some kind of voodoo magic? I even searched my sheets for needles, but still, no satisfying answer.
Finally I was able to solve that mystery. For all those guys where dumped because of unexplainable scratches the answer is simply: It’s the mighty electricity! Specifically, the one that is produced when you wear certain fabrics. I discovered that, when I pull of a shirt, sometimes enough electricity is produced to actually cause a scratch on my back.
