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!!"
