The biscuit represents a penis and the hallway represents the enormous asshole. Usually due to the fact that the man or woman has had many many sexual partners which has stretched the anus walls to the size of a "hallway".
Having sex with Chris is like throwing a biscuit down a hallway. I don't know how anyone can make gravy from this.

In this fun phrase the biscuit represents a penis and the hallway represents a homosexual male's enormous asshole. Usually due to the fact that the man has had many many sexual partners which has stretched the anal walls to the size of a "hallway".
