homo erectus 

huh huh.

homo erectus is a predecessor of modern humans. Members of this species had tools made of hard wood. They stored them inside orifices. And they spent most of their time impaling things with their long rods.

They used to grunt a lot, especially while impaling things. They drew graffiti on cave walls showing them trying to mount and stick their poles in horses and other animals.

homo erectus is a very cool name for cavemen (and women?).

dumbo erectus 

n. Dumbo erectus is the next step in human devolution. With a lower IQ than homo sapiens, and yet a normal human stride and a keen taste for fashion, dumbo erectus is the product of generations of breeding between shallow homo sapiens. The devolution towards dumbo erectus began with the invention of the television. Dumbo erectus can be found living within all modern homo sapiens populations, but higher concentrations are found in North America, with the center of population in Hollywood, California.

Cyndi, don't linger too long on Hollywood Boulevard, you might be jumped by dumbo erectus and forced to give birth to born again Christians.
