The videos were taken Thursday night at the Mokai Lounge in South Beach, Miami, according to NBC6.

The multiple videos, which aren't embedded due to the nature of the content, show a woman in lingerie riding the animal until she was flung off it when the horse bucked, the Palm Beach Post reported. There is also a large group of people surrounding the animal, which "became startled," WSVN reported.
