Where Did This Word Come From F--K

[WBDaddy]

The F-word is actually a very important tool that I use when working on my (modern) car. It is an incantation that helps reach or loosen a stubborn part and is also used to express my opinion to the engineers that designed the car.

Ah yes, nothing like the threat of violence, liberally seasoned with F-words, to get a stubborn mechanical or electronic subject to capitulate (not copulate, mind you) to your will.
