The word "Ashwini" means "Horse" and, in this context, the word Mudra means "attitude". Therefore, this mudra can be translated as "the attitude of horse".
Why the name of this Gesture is "Ashwini Mudra"?
If you watch the anus of a horse, you will see that the horse very often does the yogic practice of this ashwini mudra: the horse rhythmically contracts & relaxes the anus muscles.
