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 as a transitive verb by women, which suggests that the metaphor is all but dead

Etymology

Origin of screw

First recorded in 1375–1425; late Middle English noun scrwe, screw(e); compare Middle French escro(ue) “nut,” Middle Dutch schrûve, Middle High German schrûbe “screw”

Explanation

A screw is a small metal rod with a notch in the top that's used as a fastener. You can attach one piece of wood to another by rotating a screw through the two surfaces. A screw is similar to a nail, but instead of hammering it in, you turn it repeatedly with a screwdriver. The spiral ridges of a screw attach it securely to whatever you screw it into — metal, wood, or a bolt with similar ridges. Etymologists aren't sure about the origins of screw, although some suspect it comes from the Latin scrobis, "ridge or trench."
