词源说明
From Middle English mone, from Old English mōna (“moon”), from Proto-West Germanic *mānō, from Proto-Germanic *mēnô (“moon”), from Proto-Indo-European *mḗh₁n̥s (“moon; month”), probably from *meh₁- (“to measure”).
The usage of "moon" to refer to the act reflected its use as a metaphor for the buttocks since 1743. It was popularised from American student slang in the 1960s.
