You might think this mild madness would be limited to cars...,err : AUTOs,...mmmmh ok Chariots. We've said " Got to go to store, but the Old Lady has my 'Wheels' !".
Here in the U.S. it's been said, on and off, (to a Man; "...you go, GIRL !".
That's, obvious direct disregard for correct speak. A sort-of cultural understanding, that the use of 'girl' is by context just a habit or way of speech...not a literal label.
But all this makes me wonder, now, what about 1700's horse and buggy. Guess is, that 'buggy' could conceivably be short for something like 'lugger-trolly'...(crappy example, I know, lol).
