Yup, it's just that the horse is working/sweating, and with the legs rubbing together, the sweat lathers/foams up. The same can happen on the neck if the horse is sweating and the reins rub on the neck. It's just like when we wash our hands. We put soap on them but when we rub them together, they lather up.
Everyone should be allowed at least one bad habit, and that's NOT owning a horse! Mares RULE! Geldings drool!
