It usually costs a lot of money but they were doing it for free (Afghan piss party)

The British officer John Masters recorded in his autobiography that Pathan women in the North-West Frontier Province (1901–1955) of British India during the Second Anglo-Afghan War would castrate non-Muslim soldiers who were captured, like British and Sikhs. They also used an execution method involving urine, Pathan women urinated into prisoner's mouths. Captured British soldiers were spread out and fastened with restraints to the ground, then a stick, or a piece of wood was used to keep their mouth open to prevent swallowing. Pathan women then squatted and urinated directly into the mouth of the man until he drowned in the urine, taking turns one at a time. This method of execution was reported to have been practiced specifically by the women of the Afridi tribe of the Pashtuns.
