If Donald Trump makes it to the general election, expect him to stick to one name when referring to his likely opponent: "Incompetent Hillary."

Much like his branding of past and present Republican rivals — "Lyin' Ted," "Little Marco" and "Low-energy" Jeb Bush — the leading GOP presidential hopeful recently debuted his new moniker for former Secretary of State Hillary Clinton.

"Incompetent Hillary doesn't know what she's talking about," Trump told Fox News' Sean Hannity Tuesday night. "She doesn't have a clue. She's made such bad decisions."

Despite previously describing Clinton as "incompetent," Tuesday marked the first time the billionaire used the word in a pejorative nickname.

Shortly after his interview with Hannity, Trump repeated his new nickname for the former first lady in a statement on Twitter.

Incompetent Hillary, despite the horrible attack in Brussels today, wants borders to be weak and open-and let the Muslims flow in. No way! — Donald J. Trump (@realDonaldTrump) March 23, 2016

Clinton's new moniker comes just days after Trump told The New York Times columnist Maureen Dowd he wanted to "get rid of the leftovers first" — presumably referring to his two remaining opponents in the Republican field – before forcefully attacking Clinton in typical Trump fashion.

But after defeating Texas Sen. Ted Cruz in Arizona, and expanding his delegate count even further over Cruz and Ohio Gov. John Kasich, Trump seems satisfied with his standing in the GOP race at the moment.

The billionaire now seems to be gearing up for a battle against "Incompetent Hillary."
