Disciple of Onan

From the Book of Genesis: Onan and Er were brothers; when Er died, their father Jacob decided that Onan should assume matrimonial duties with Er's childless widow. However, instead of completing the act, Onan "spilled his seed on the ground". God considered this an evil act and Onan was slain for it.

A man was observed on the London Underground practicing the faith of a Disciple of Onan. Police were called and apprehended the suspect.
