Here's why:
* "Hind" is usually used to refer to the rear part of an animal, like "hindquarters". This doesn't fit with typical cowboy language.
* "Hind" could be a misspelling of "hide", which is a common term for an animal's skin. Cowboys would use "hide" to refer to a tanned animal skin used for making leather goods.
* "Hind" could also be a misspelling of "hined", which is a variant of "hied" meaning "to hasten or hurry". This is a less likely scenario in cowboy slang.
Without more context, it's impossible to say for sure what "hind" means in this instance. If you can provide more information about the phrase or situation where you heard it, it might be easier to determine the intended meaning.
