Australian Mudflap

The act of motor boating a woman's ass, sticking as much of your face into the anal cavity as possible. Upon performing this act, she begins to involuntarily defecate (shits) in your face. Unphased, you continue with your fowl deed, flinging feces in all directions.

After giving Jenna an Australian Mudflap, my face was covered in poo and there was a fair amount of shit everywhere.
