In more than one language I know, when someone keeps nagging about a subject that you do not want to hear about but you have to because that person is your boss or your wife and their talking goes on and on until they cause damage to your brain, one says something that literally translates to they fucked my brain.
- in Arabic " ناك راسي يازلمة"
- in Russian "ебать мозги"
I know hit my nerve but that doesn't convey to what extent the damage is done to the brain, do you have anything much stronger?
