Under no circumstances. This expression, which means just about the same as “not if your life depended on it,” dates from the late nineteenth century. It appeared in print fairly often from 1900 on, as in Jack London’s The Valley of the Moon (1913): “‘You’d vote the socialist ticket.’—‘Not on your life.’” Its positive counterpart is you (can) bet your life.
