Slaanesh

Slaanesh, also known as the Dark Prince, the Prince of Pleasure, the Lord of Excess, the Perfect Prince, and even the Prince of Chaos in the Imperium of Man, is the Chaos God of pleasure, excess and decadence. Lust, pride and self-indulgence are the hallmarks of all who follow it. Slaanesh is the youngest of the four major Chaos Gods, having come to full sentience within the Immaterium only during the 30th Millennium. While generally referred to as a “he” by Humans and as a female by the Aeldari, Slaanesh is actually neither gender, combining characteristics of both and perfecting them. The name Slaanesh is a corruption of the Aeldari term Slaaneth (Slaa meaning “ecstasy” or “pleasure” and Neth meaning “lord” or “prince” in the Aeldari Lexicon; hence, the “Prince of Pleasure”).” See also: Disciples of Slaanesh
