This term was requested by Peter for his translation of The Time Machine. He sent a phrase to Okrand asking if it had the right meaning. This is the conversation went:

MO: Given the literal translation of the Klingon ("sophisticated copulator procedure" or something like that), I’m guessing that the needed word is "eroticism" — that is, a noun not an adjective. Maybe vIqraq "artifact, work of art" instead of mIw Hoy? And maybe even parmaq rather than ngaghwI' since Klingon "love" is on the aggressive side.

PK: It actually is "eroticism". It is not elaborated whether it is artwork or the "art of lovemaking". Would parmaq meHghem work?

MO: Yes, assuming that it's referring to erotic art. meHghem "art" includes visual art and performance art.
