When you are having sex with a girl, but then you turn around and take a steaming shit on her butt, returning the fecal matter to a place where it knows.
We were getting pretty hot the other night until he gave me the old "Return to Sender", and now my sheets will never be the same...

After performing The Oden on a fortunate female, you send the severed head to the female's place of residence. Its funny because, not only is the severed head decaying in a box, but nobody's gonna be home to open the perishing package.
I sent "The Oden's Return to Sender" first class priority mail yesterday. The package better arrive at her place tomorrow or I'm gonna be pissed with the post office!
