rowback
n.— «Have you read Okrent on that “squirrelly journalistic dance step known to old-timers as a ‘rowback’ “? That’s when a news outlet tries to cover up an erroneous story with a new story that conveniently neglects to mention the first one.» —“Our Man Dan” by William Powers National Journal Apr. 10, 2004.
