Echoing now PM-elect Tony Abbott's feisty comment in one of his debates against defeated Kevin Rudd, "does this guy ever shut up?", economist and former Julia Gillard adviser Stephen Koukoulas engaged in a slew of Twitter backlash against Mr Rudd:

Time now for Rudd to leave politics. A poisonous man who takes all the credit for Abbott's win. I assume Abbott will thank Rudd first

Come on Kevin. Just leave gracefully. — Stephen Koukoulas (@TheKouk) September 7, 2013

Flush.

What a dreadful man. Go away forever. — Stephen Koukoulas (@TheKouk) September 7, 2013

Wow. What. Great loss yay. Yay. Yay. Go shitbag.

Does Rudd realise he has lost? — Stephen Koukoulas (@TheKouk) September 7, 2013

What an absolute shit show. Go Kevin. Bye. Loser. Spoiler. Snake.

And now, Mr Rudd, once both social media and camera sweetheart - Twitting his own selfies, launching campaign ads and appearing in music videos - snuggled hidden away in his home at Norman Park in Brisbane's inner east.

Apparently, defeated Mr Rudd decided to hide away from the media and his family members were equally elusive of his whereabouts.

Outside their home, media were waiting.

Mr Rudd's daughter, Jessica Rudd and husband Albert Tse, then came with baby daughter Josephine in tow.

As believed, Mr Rudd will spend some time babysitting Josephine until all the fuss subsides.

A long-time Rudd staffer visited the house at about late afternoon telling the media off.

"There's no news coming out of here today," said the staffer.

Shortly after, Ms Rudd and husband leave the house and came back with plastic bags of groceries.

When asked about how the family was accepting defeat, Ms Rudd was abrupt.

"Fine, thanks," Ms Rudd told a Courier Mail reporter.

Mr Rudd's sons, Marcus and Nicholas, were also seen inside the house. However, there were no other members of the Australian Labor Party or any other Rudd supporter who visited the "hiding" Mr Rudd.

Meanwhile, while the media frenzies, a representative said that Mr Rudd will not appear in public until he formally transfer the prime ministership to Mr Abbott at The Lodge.

"The timing of that would be up to the new prime minister," the representative told the Courier Mail.

All these - Twitter backlash and hiding - boiled down to Mr Rudd's insincere and haughty concession speech.

Mr Koukoulas was not alone being disgusted by Mr Rudd's speech.

Bill Glasson, whom Mr Rudd referred to arrogantly in his speech, was also sickened of Mr Rudd.

"It would be un prime ministerial of me to say Bill Glasson eat your heart out, so I won't. The good people of Griffith, the good people of Brisbane south side, it is such a fantastic community and I thank them for their support," said Mr Rudd in his speech.

For which Dr Glasson responded bitterly.

"I thought that was rather churlish. If he's going to pull a by-election sort of short term, it could possibly interest me. If he's going to go the three years - and I do hope he goes three years for the sake of the people of Griffith - then I'd have to look at the situation then. So he doesn't need to be too sanctimonious with his sort of smart-arse comment last night," Mr Glasson said.
