A very large dinosaur, akin to the T-Rex, but much more fail... It was probably the first to die during the giant meteor shower. Now used in the Mid-Michigan suburbs as a term for people who tend to fail on a scale almost beyond epic. In fact, their entire existence seems to be FAIL.

Person1: Have you seen Jimmy?
Person2:Yeah, I heard he tripped walking down the hall, fell into a girl, broke his leg, and got charged with sexual harassment.
Person3: Jimmy's a total Failasaurus Rex.
