Opposition Leader Tony Abbott's bid to win female votes may have taken a hit after what the Greens described as an ''inappropriate'' sexual phrase he levelled at his counterpart.

Asked whether he would take up Prime Minister Julia Gillard in more debates, Mr Abbott ridiculed the invitation, before saying: "Are you suggesting to me that when it comes from Julia, 'No' doesn't mean 'No'."

The phrase has become notorious, being referenced in several high-profile court cases, especially when it comes to a women's right to not have sex.
