succubus

Definitions

1. A medieval term for an evil spirit or demon who assumes the form of a woman and is supposed to lie under sleeping people, particularly sleeping men, and have sexual intercourse with them. Its male counterpart is known as incubus. Plural: succubi. Humorously defined by Roger Mellie in Roger's Profanisaurus (1998) as: ' A phantom night-time cock sucker once thought to be responsible for nocturnal emissions.' (I do enjoy Roger's version.)

2. The person who assumes the bottom or passive position in sexual intercourse.
