IF he didn’t know what “mansplaining” was before, he certainly will now.

On only his second day as Prime Minister, Malcolm Turnbull copped a stunning smackdown by Labor’s deputy leader Tanya Plibersek, after failing to give her a satisfactory answer in Question Time.

Asked by Ms Plibersek, the Opposition’s foreign affairs spokeswoman, how much money he would restore to the foreign aid budget after $11 billion in cuts by his predecessor Tony Abbott, Mr Turnbull launched into a rambling non-answer.

“If all she’s interested in is making an allegation, making a political argument across the dispatch box, that is fine. But it’s a complete waste of question time and now the honourable member is asking more questions by way of interjection. Ask the substantive question about foreign policy, about foreign aid,” he said during his longwinded response that went for well over a minute.

Ms Plibersek was having none of it.

“Mr Speaker, I’d rather have an answer than the mansplaining I’m getting.”

Mansplaining is to “explain something to a woman, in a way that is patronising because it assumes that a woman will be ignorant of the subject matter”, according to the Macquarie Dictionary, which crowned mansplaining as its word of the year in 2014.

Ms Plibersek was then ordered to get back in her seat by Speaker Tony Smith.

The accusation reportedly left some in the Parliamentary chamber scratching their heads at exactly what Ms Plibersek meant.

Just days ago, Hollywood actor Matt Damon was accused of interrupting a female African American filmmaker to mansplain the concept of racial diversity in movies in a cringe-worthy conversation caught on tape.

Here’s the full exchange between Mr Turnbull and Ms Plibersek.

Plibersek: “Will the Prime Minister confirm how much money he will restore to the foreign aid program, after the cabinet he was part of cut the budget by $11.3 billion dollars?”

Turnbull: “I thank the honourable member for her question and the answer which she again she knows she will get is that any decisions about the foreign aid budget will be made by the cabinet.

“The PM is in no position or should be in a position to make an off the cuff policy decision like that. This is talking about enormous sums of money. Is this the type of government the Labor Party would run, but you just have billions of dollars — yes, it is. Of course it is!

“It absolutely is. It absolutely is. No cabinet process, no proper examination of the competing needs. The honourable member has 18 billion dollars of foreign aid commitments completely unfunded. The reality is as the honourable member knows, if the honourable member wanted to get a serious answer she should ask a serious question.

“If all she’s interested in is making an allegation, making a political argument across the dispatch box, that is fine. But it’s a complete waste of question time and now the honourable member is asking more questions by way of interjection. Ask the substantive question about foreign policy, about foreign aid.

“Ask it of the foreign minister and you can have an intelligent discussion, but instead here we have the entire House of Representatives assembled and the time being wasted by the honourable member.”

Speaker Tony Smith: “The point of the order being?”

Plibersek: “I’d rather have an answer than the mansplaining I’m getting.”
