According to Murray MacLeod on this mudcat.org thread in 2002, "Falorum" is the genitive plural of the Latin "phallus" and should be more correctly spelled "phallorum". "Dingdorum" is the genitive plural of the Latin "dingdus" which transmuted over the centuries to the the more modern "dong".

Of course, it is immediately obvious to any Latin scholar that the use of the genitive plural case is grammatically wrong, and that the line... should read "He's got no phallum, he's lost his dingdum" (ie. the accusative singular case would have been more correct.)

    And I found his faloorum, fal liddle all day.
    And I found his faloorum, he got my ding doorum,
    Maids when you’re young never wed an old man. )
