Acronym. Discerning Ethical Slut. A person, usually female, engaging in consensual non-monogamy, but is characteristically selective with whom s/he has relations and thus will have fewer partners than the typical slut. Variation of "ethical slut," a term from the 1997 Dossie Easton narrative "The Ethical Slut."
Jane is a DES because she has been engaged in consensual non-monogamous simultaneous relationships with John, Rick and Steve, who all possess characteristics necessary for her to date someone: wealthy, attractive, intelligent.

Exact history not known, but widely used in several circles to describe the act of having a brief (less than 1 hour)sleep early evening to re-charge batteries for evening's entertainment. Not to be confused with a "big sleepy John", which is a more straightforward early night with no intention to get up again.
Big night last night, and I'm out agian today. I am just off for Des first....
