In modern usage, an orgy is a sex party where guests engage in promiscuous or multifarious sexual activity or group sex. An orgy is similar to debauchery, which refers to excessive indulgence in sensual pleasures. Swinger's parties do not always conform to this designation due to the fact that at many swinger parties the sexual partners may all know each other or at least have some commonality among economic class, educational attainment or other shared attributes. Some swingers contend that an orgy, as opposed to a sex party, requires some anonymity of sexual partners in complete sexual abandon. Other kinds of "sex party" may fare less well with this labelling.
Participation in an "orgy" is a common sexual fantasy and group sex targeting such consumers is a sub genre in pornographic films. The term is also used metaphorically in expressions, such as an "orgy of colour" or an "orgy of destruction" to indicate excess, overabundance. The term "orgiastic" does not generally connote group sex and is closer to the classical roots and this metaphorical usage.
Unjustly the most vivid link of Roman religion and sex or orgy is with the Vestal Virgins but in fact they were just that, virgins. Breaking their vote of chastity was punished with a whipping and being buried alive. I suppose that similarly to porno films involving nuns the notion of transgression is likely to make the Vestals quite titillating to the modern public and possibly to their contemporaries also. However their public position was so elevated that any misdemeanours would have been quite limited and severely punished with capital punishment. Although, now that I think about it, there was a direct tunnel joining the Palace on the Palatine hill and the Vestals' temple.....
