show someone one's etchings

Verb

 * 1)   to show a place where people can engage in sexual intercourse

Usage notes
Ian Stuart-Hamilton's An Asperger Dictionary of Everyday Expressions notes that this is rarely used as "an invitation to have sexual intercourse", presumably speaking of real-life situations. However, this sense remains a common trope in fiction.
