To cut the string on your banjo (circumcise one's self) in the act of sex and then proudly announcing it to the public.

To poop in one’s hand, and gently smear it on someone else’s back without the other person noticing. Giving someone a dirty ellie is a sign of great affection, and is only given to the closest friends. A dirty Ellie is usually performed on bare backs, but can be substituted for over-the-shirt in a pinch.
