Saudi Death Mask
(n) A sexual act in which one partner defecates in the other partner's mouth and then wraps their entire head in clear Saran Wrap. In order to be a successful Saudi Death Mask, the act must result in the death of said partner.

origin: This originated in Saudi Arabia as a means for the Sultans to dispose of their unwanted wives. It was considered an honor to be Saudi Death Masked for many years until, in 1967, human rights groups quelled the age old tradition. There hasn't been a public Saudi Death Mask performed since then; however, many believe they still are conducted in private.
