A dinosaur is an old man, made famous by Ke$ha's song. He frequently hits on younger women, some as young as 12. He can be anyone from a middle school math or science teacher to already retired at "an old folk's home." They slick back their hair, charge into a bar, and offer to buy a girl a martini, olive and everything. They are sure to be a creeper- don't listen to anything they say-even if they have a sexy tank of oxygen! A cougar is the equivalent of this, but the female type. Dinosaurs are more common.
