1. A ginger's ball sack, referring to the rust-like color of the pubic hair

2. A sexual act which incorporates tea bagging as well as the cleveland steamer where one partner "poops" on the other's chest and then dips the scrotum into the feces. (in order for this to be defined as a rustysack, the poop must be reddish-brown in color).

3. An incorporation of the chlojob

4. The dipping of the testicular sack in poop (preferably with the poop on boobies)
After coitus, I tried getting her to go for the rustysack but I could not say I was surprised when I was turned down. It is a rather messy act which requires much cleanup.
