showers

   1. deviant sexual activity

   A code word in prostitutes' advertisements, from the penchant of some males for sexual antics involving the urine of another or, in the jargon, a golden shower:

    The gangs control drugs. Hooking, that's mostly for oddball stuff now, golden showers, Greek, not straight sex. (Turow, 1993)

   A brown shower is offered for customers who prefer faeces. A showercap in this company is either a contraceptive sheath or a diaphragm.

   2. see take an early bath

   3. gas chambers

   Part of the Nazi pretence that prisoners arriving at an extermination camp were merely being disinfected. Also as shower baths:

    His first job was to work in one of the ante-rooms where prisoners had to remove their clothes before going through a door to the 'showers'. (C. Booker in Sunday Telegraph, 29 January 1995, writing about Auschwitz)

    But it might be acceptable to evacuate the children and the old people (presumably to 'shower baths'). (A. Clark, 1995, describing German policy planned for Leningrad in 1942)
