Penisaurus rex 

A beast with the world's largest 5 inch penis. It should be noted that the 5 inches is in reference to the radius of the penis. When erect, it can extend up to 15 kilometers in length.

The word "Penis-" is the latin word for "Tail" and the term "rex" is also from the latin word "king". Hence "Penis King"

Kingdom - Anamalia
Phylum - Chordata
Class - Mammalia
Order - Penisauria

Penisaurus rex is often abbreviated to P-Rex. The P-Rex is often synonymous with the word AVBP.

The most common prey for the Penisaurus rex is the Danfag

In some cultures, the P-Rex is referred to as "Moosa, the beast with the 2.5 ton AVBP". It sometimes suffers from back problems.

The Penisaurus rex used its AVBP to crush the Danfag

Johnny is the Penisaurus rex.

Occasionally, the Penisaurus rex would suffer from Penisclerosis and would get a 28 hour erection.

When the P-Rex caught a case of Penisclerosis, it used its AVBP to smack Danfags across the face.

People worship the Penisaurus rex by repeatedly chanting "Moosa-Bhai!! Moosa-Bhai!!"
