A clapsacker is a word invented by my wife. Who likes to make up random words. The definition is someone who does everything exactly by the book, to the point of taking all the fun out of things in life. It originated when I told her, that she shouldn't plug her phone into the car when it wasn't running because it would drain the battery. She said, WTF, why do you always have to be such a clapsacker.
Charging my phone without the engine running is not going to drain the battery. Stop being such a fucking clapsacker all the time!
