The “Duke of Marlborough Effect” was mentioned by Richard Dawkins to refer to the increase in masculine libido that results from experiencing a victory, whether directly or vicariously. This was so-named from an entry in the Duchess of Marlborough’s diary, “His Grace returned from the wars today and pleasured me twice in his top-boots.” Male athletes tend to experience elevated testosterone levels before a contest; those who win tend to maintain afterwards those elevated testosterone levels, but the testosterone levels of losers drops dramatically afterwards.
There will likely be a lot of canoodling in Old Boston now that the Red Sox have won the Series due to the Duke of Marlborough effect and the subsequent release of proper Bostonian inhibitions.
