Porcupoo 

When you take a dump that is so thorough and detoxifying that the hairs on your arms and legs stand up.

I just had a total Porcupoo. It was awesome. Here, look at my arms- the hair is still standing up.

porcupotamus 

The terrifying cross of a porcupine and a hippopotamus. Extremely aggressive and territorial. Can weigh up to 1,700 pounds, and can achieve land speeds of 40 MPH. Quills measure up to 5 feet long, and up to 1 foot in circumference at the base. Mostly herbivorous, with a pronounced taste for oatmeal and an occassional serving of chicken tikka.

"Larry, please stop your porcupotamus from trying to couple with with my dog."
