TIL going "balls to the walls" originates from aviation lingo - Lemmy.World

I never knew and got curious and looked it up. I guess it makes more sense than slamming your testicals against the wall.

Not to be confused of course with “balls deep”, which is exactly what it sounds like
It’s when your shaft is so damn deep that you can only barely make out your ball amidst the shaggy rough entanglement. Courses like Oakmont Country Club, Ko’olau, and Pinehurst are some examples that can challenge even top golfers.
