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 person who has been employed for a long time by a corporation, university, or organization. Generally used disparagingly by younger persons who regard this person as a general obstacle to progress, or one to their own personal advancement. The expression implies obsolescence on the part of the person so described, whether factually or not.
The English Department was filled with dinosaurs who were on the faculty for more than thirty years. They should set a maximum limit on the number of years a person may be on the faculty!
