What does a screw has to do with wishing bad things to happen to someone?
Why if "screw" means:Specifically, a kind of nail with a spiral thread and a head with a nick to receive the end of the screw-driver. Screws are much used to hold together pieces of wood or to fasten something; -- called also wood screws, and screw nails"....
Why do people say to others "screw you" to wish them bad things happen to them?
What does a kind of nail with a spiral thread and a head with a nick to receive the end of the screw-driver has to do with wish someone bad?
It means the same as "f. you", that's why the 'screw' reference.
I don't know if you've noticed but for example people say "f. you" and they don't even think about what it means or refers to, people say it only because it 'sounds' vulgar.
People's always looking for saying things in many 'new' ways.
Then the more people use it, the more they eventually forget what it means. XD
Well, this is the truth, I hope it was helpful.
