The geasy spulge left in your ass after shitting, if not wiped properly. It can sometimes occur even after a thorough wiping because occasionally your rectum may seep. Warm and humid weather may also intensify this harsh reality.
After taking a growler, I realized i had a bad case of monkey butt on the par three 5th. There was no outhouse around!
