Bodily orifice

Robert Novak, a US TV guy, hit a pedestrian yesterday while driving his black Corvette. I was reading about an accident he had earlier but they couldn't report what he actually said so they wrote this (below):

In 2001, the longtime political columnist cursed at a pedestrian on the corner of Pennsylvania and 13th St., NW, for allegedly jay walking.

“’Learn to read the signs, [bodily orifice]!’ Novak snapped before speeding away,” according to an item in the Washington Post’s Reliable Source column.
