Elizabeth Daingerfield Zwicky ranted in Facebook a while back, when Mothers Day loomed:
As a breeder, let me go on record as saying get over it already and stop turning my ability to produce loin fruit [she meant to type “loinfruit”] into an excuse to plaster the world with commercialized guilt and stereotyping.
First, there’s breeder, which has two salient senses here (both applicable to Elizabeth): ‘a heterosexual’ and ‘someone who has had a child’. But her posting was noticed mainly for its use of loinfruit ‘child, children’, which was new for some readers and struck them as inventive and entertaining.
Elizabeth was in fact using an expression she had learned some years ago on the Usenet newsgroup soc.motss. She and I picked it up from Gwendolyn Alden Dean, who referred to her son as “the loinfruit”. So I asked about the expression on the Facebook descendant of the newsgroup and got the local history of the expression.
