A MOVE dubbed the shoulder-shimmy may well have been enough to hand Hillary Clinton voters' hearts in the first Presidential Debate.

The Democratic nominee succeeded in putting Trump on the defensive, attacking him over his refusal to release tax records, past comments about race and his attitude towards women.

Shortly after the debate most major US media outlets agreed Republican nominee Donald Trump had been trounced.

"Donald Trump aggressively blamed the nation's chronic problems on Hillary Clinton yet found himself mostly on the defensive," was the lead from the Washington Post in the moments after the debate ended.

"Clinton…delivered a strong performance in which she demonstrated a command of policy and a sense of humour," the conservative leaning CNN reported.

"Clinton dominated a final series of debate exchanges with Trump about national security and gender, telling voters they could not trust her opponent with nuclear weapons and warning that he does not respect women," stated the New York Times.

Trump for his part offered scant defences to Clinton's well researched attacks, for example when questioned about unpaid debts, left over from some of his four bankruptcies, Trump delivered a clanger.

"If you want to change the laws, you have been there a long time, change the laws. I take advantage of the laws of the nation," he said.

However the moment which many say best summed up the exchange happened when Trump attacked Clinton's temperament.

"I think my strongest asset, maybe by far, is my temperament - I have a winning temperament, I know how to win, she does not." Trump said.

Clinton responded simply with: "Woo, okay" before shaking her shoulders in a move social media has since dubbed the shoulder shimmy.

The audience, which had reportedly been asked to keep quiet, burst out in laughter.
