It's also not a legal term just because it has the word court in it. It's a phrase that's been around a long time. If you or anyone else doesn't understand it, and I point it out to you, with the help of a dictionary, what the fuck do you want me to do? Say, 'oh i'm sorry, you've made up a different meaning for that phrase than what it means. I should just accept your meaning then?' FML.
