Pregnasaurus 

A large lumbering animal with an extended stomach and a lifespan of about nine months. Animal is prone to ligament pain, especially as it reaches maturity. Know for uncontrollable mood swings, strange eating habits, and a cooing noise made when near children's clothing.

The pack of pregnasaurus waddled into the baby section of the department store and began making strange cooing noises. Spectators were amazed by the gentle nature of the pregnasaurus until one became ferocious with hunger and proceeded to hunt and devour a candy bar.

Pownasaurus 

Typically a 12 year-old boy, whose balls have no quite dropped yet. Playing COD or Halo, screaming at the top of his squeaky annoying voice whenever he feels he has accomplished something of importance. Not to be confused with the Pownasaurus-Rex . A middle-aged balding version of the pre-teen Pownasaurus. Who, despite the dropping of balls, still sucks at life.

"AHHH DOOOD! I am totally like the POWNASAURUS right now! I definately just jumped into that vehicle, damn right, POWNASAURUS on the prowl!!!"
"Man...STFU you squeaky voiced beeeyyotch!"

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

The Penisaurus rex used its AVBP to crush the Danfag

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!!"
