A large and/ or unattractive woman found at the bar during last call. Usually found preying on intoxicated men who have struck out throughout the evening. Taking one back to her place will often result in a coyote ugly.
After the rough night I had striking out, I decided that I would have four more shots and settle for the rhino at the end of the bar.

Get the the rhinomug. The act of coming up from behind someone who is not paying attention, forming a heavy fist, and going through the legs for a punch to the nuts. As the person is stunned, the victim then is hurled into the air when the person, from behind, lifts at an upward angle.

Get the Rhinomug. A name for an attack performed by forming one's hands into a fist shape with the thumbs together and pointed outward. The attacker proceeds to send their "hand rhino" swiftly upwards into the asshole of the victim.
