1. Sillysaurus is a word very similar to the expression silly goose. It only differs in the sense that the said person is being so silly it's as if they were from the dinosaur era. It is used to describe someone acting very silly. In other words if someone is being funny but ridiculous, they're being a sillysaurus.

2. Sillysaurus can also be used to refer to someone who often behaves in a very silly but funny way.

sillysaurus

A carousing "dinosaur" sorostitute that gets way too smashed to handle her unsightly features. Liable for lawsuits by dancing on bars and breaking too many light fixtures with her "tail" (i.e. fat ass and large hair.)
