derpiesaurus 

A dinosaur that is everything derp. A derpiesaurus is created when you mix Herp DNA with a Derp DNA. When the derpiesaurus growls, he/she seemingly sounds like a person who is saying Herp da Derp. It sounds 9000 times better than when a human says it.

Derpiesaurus is very rare and has been only spotted by a few people. Some have spotted the amazing creature when someone says or does something extremely stupid or obvious. Other times, people have hallucinated a derpiesaurus, such as when trippin on LSD or shrooms. Scientists are still unsure of its existence though

man 1: I didn't know africa had white people living on it!

man 2: ... DUDE LOOK OVER THERE

man 1: OH FUCK WHAT IS THAT?

man 2: OH MY FUCKING BALLS! ITS A FUCKING DERPIESAURUS. FUCK. MY LIFE IS COMPLETE NOW!
