I had to Google it, so I'll present my findings for other confused anons. In elder ring, some npc calls the player character "maidenless" in the sense of "does not have a maiden to sleep with," so basically "lol virgin"

And now I'm torn between sighing about us using a virginity reference as an insult, being annoyed about the hwtwronormativity of it, and pointing out that calling someone a virgin here is like being surprised about finding fish in the ocean.
