Who or what are they and what do you do if you run across one?

We have the  goal. Now we need the methods...

From Wikipedia: "In medieval legend, a succubus (plural succubi; from Latin succuba; "prostitute") is a demon which takes the form of a female to seduce men (especially monks) in dreams to have sexual intercourse. They draw energy from the men to sustain themselves, often until the point of exhaustion or death of the victim. From mythology and fantasy, Lilith and the Lilin (Jewish), Lilitu (Sumerian) and Rusalka (Slavic) were succubi. While they had the appearance of a female, most sources claimed they did not possess a vagina-- they had a thingy, and were actually male demons. (Source: The New Encyclopedia of the Occult, John Michael Greer)" ALso.. from the same site: "In Western medieval legend, an incubus (plural incubi; from Latin incubare, "to lie upon") is a demon in male form supposed to lie upon sleepers, especially on women in order to have sexual intercourse with them. The Incubus drains energy from the woman it performs sexual intercourse upon in order to sustain itself, and in most cases either kills the victim or leaves the victim alive but in very weak or fragile condition. A female version was called a succubus."

Hmm.. so would it be an insult if someone were to call someone a succbus?!?!?
