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!"

pandasaurus 

The pandasaurus is usually a peaceful creature, but when disturbed, it turns into a ferocious dinosaur like monster. It's main diet consists of large amounts of bamboo, but can really digest about anything. The pandasaurus look like any normal panda but is three times larger and has longer claws on their paws. During their life, the pandasaurus mostly sleeps and eat, and rarely spend their time to reproduce. Because of this, there are few of them left on Earth. If you ever encounter one, do not piss them off or else they will eat you. The plural of pandasaurus is pandasauri. If you want to learn more about the pandasaurus thumbs up.

You: Hey look mom they finally have a panda at the zoo.

Your mom: No, dumbass, it's a pandasaurus.

You: Oh...can we get cotton candy at the zoo.

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
Family - Penisauridae
Genus - Penisaurus

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!!"
