Usage: The use of this otherwise utilitarian word in a sexual sense, though recorded in an 18th century slang dictionary, does not appear to have really taken off until well into the 20th. Although a classic example of the anatomical metaphor for the sex act seen from the male point of view, it can be used with a woman as the subject, which suggests that the metaphor is all but dead
