Sheared one of the new studs I was installing for my intake/exhaust, barked my knuckles on the water pump.
It was a quiet night, garage was open, anyone within within about half a block probably heard a very emphatic "shitfuck!"
I've been turning wrenches enough that when a bolt is going to go I can usually predict it in my hindbrain. Far enough back that I'm not surprised-surprised, but not far enough forward for me to stop it.
Usually just enough time to ensure the language centers of the brain are primed, thus an understandable phrase.
If I'm doing something else, it usually gets the same incoherent hooting you're talking about.
