Emulate a horse means to imitate the movements of a horse, such as a TROT. The term 'TROT' is a four-letter word used to describe the gait of a horse in which the legs move in diagonal pairs. This type of movement is often seen in horse racing and show jumping. It is also used in some forms of dressage, where the horse is trained to perform specific movements. Emulating a horse can be done by humans, either on foot or on horseback.
