Confused about American and English words for stuff!!?

They are both called bucking (a rodeo bronc is a bucking horse). Out here on the west coast when I horse kicks out once or twice we say the horse bucked, but if they keep at for multiple jumps and have their nose between their knees and have all four feet coming of the ground with a big hump in their back we'll say they "cut in two" or "went to bucking." The biggest difference is that one can kick out while still going forward, if they get all feet off the ground they aren't usually going forward and are harder to ride out. Horses have different styles of bucking some kick out and some have what we call a big drop which are the ones that get their front end of the ground. A great bucker will do some of both and through in some twists and turns as well as have little to no forward motion.
