This is the same issue I came across, after retiring south, regarding "saddle".
It took me a while to figure out what the locals meant when they said "does that horse saddle?"
The horse in question was older, well broke and being ridden on the trails, so I thought maybe they meant HOW WELL did the horse stand to have a saddle put on; even though that didn't make sense.
"Saddle" or "saddling" is a term used in the south to say whether or not a horse gaits, generally meaning to perform a rack or a single foot.
I've been here ten years and still have to stop and think about the context when I hear someone say "that horse will really saddle, when you ask it"
