The avocado of the prehistoric age. Green and often bumpy, the dinosaur means "Terrible Lizard". Just like the avocado; a terrible fruit. Dinosaurs are large reptiles, but many believe the CIA simply buried their bones to discourage time travel. It has worked, because obviously I haven't met Elvis yet. Curses.
I am not frightened of that 19 foot to 20 foot T-Rex dinosaur, because of its relatively stubby arms, despite its reptilian flare and tail intensity.

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.
