According to lexicographer Ben Zimmer, the term originated in Northern Ireland in the 1970s. Zimmer cites a 1974 letter by history teacher Sean O'Conaill which was published in The Irish Times where he complained about "the Whatabouts", people who defended the IRA by pointing out supposed wrongdoings of their enemy:
I would not suggest such a thing were it not for the Whatabouts. These are the people who answer every condemnation of the Provisional I.R.A. with an argument to prove the greater immorality of the "enemy", and therefore the justice of the Provisionals' cause: "What about Bloody Sunday, internment, torture, force-feeding, army intimidation?". Every call to stop is answered in the same way: "What about the Treaty of Limerick; the Anglo-Irish treaty of 1921; Lenadoon?". Neither is the Church immune: "The Catholic Church has never supported the national cause. What about Papal sanction for the Norman invasion; condemnation of the Fenians by Moriarty; Parnell?"
