An older man on the prowl for a younger woman and by definition, the gender opposite of the cougar. The rhino derives his name from his appearance because the specimen is more often than not both horny AND ugly. The rhino is usually found in warmer locales and can be spotted wearing either a flowered or pastel shirt (with 3 buttons opened to expose a mature mane of chest hair) tucked into khaki shorts and sporting boat shoes. Also look for horrendous dance moves, a white man's overbite, male pattern baldness and a penchant for picking up the bar tab.

Equivalent to "the elephant" except the penis is erect.

Pull out pockets of jeans, stick penis out of fly.
Relax man, the elephant's fine. If he was doing the rhino, that's f*cked up.
