A person so believing of what you tell them, the size of their gullibility equals that of a Dinosaur.

Whitney believed me when I told her George W. Bush is my butler, what a gullisaur!

Guñisaurio 

The Guñisaurio is a dinosaur type creature that dates to the late 20th Century. Originally it hails from South America, but some claim the Guñisaurio has been spotted in parts of North America and Europe. Typically, it can be found yapping, napping, or biting things such as kern, marrano and other delicacies. If ever thing you see the Guñisaurio, maintain a safe distance and call for help...it can be a wild and unpredictable creature.

I was at the gym the other day and I saw the Guñisaurio. I will never be the same.
