Is it possible the phrase onacup comes not from onanism (quite an obscure foreign word for japan) but rather onna, the word for woman?
Actually "Onanism"/"Onanie" and variants are quite common Japanese terms for masturbation. Here we have a Roman Porno film title listing, "スペシャルONANIE" meaning something like Special Masturbation. Dekkappai (talk) 18:00, 20 December 2007 (UTC)
