The suffix jo (Korean: 조; Hancha: 組) is a Sino-Korean word which describes a group of people, roughly analogous to the terms "squad" or "team".
A 2015 Fox News article, citing the South Korean newspaper The Chosun Ilbo, says that "pleasure squads" have reportedly existed since the administration of North Korea's first leader, Kim Il Sung.

Martin writes that Kim Il Sung was not just interested in pleasure, but also in rejuvenating himself through absorbing a young virgin's ki, or life-force, during sex.
