A male who appears to be an adult but has the emotional maturity of 9 month old. A babysauraus is especially deceptive because he is usually tall,well built or very muscular.
Jim is so tall and good looking. He's also a line backer in the NFL too bad all he ever does is whine about the fact that he has no friends. Jim is a babysaurus.
