North Korea took an official swipe at South Korea’s new president on Wednesday in remarks widely seen as a sexist jab.

An unidentified spokesman for the North Korean National Defense Commission’s Armed Forces Ministry accused South Korean officials of “warmongering” orchestrated by the “venomous swish of skirt made by the one who again occupies” the presidential Blue House.

The statement is a veiled jab at South Korean president Park Geun-hye, who lived in the Blue House for five years as first lady to her father, late dictator President Park Chung-hee, reports The Associated Press.

“Swish of skirt” or “chima baram” is a derogatory Korean phrase used to criticize women seen as overbearing and manipulative.

It also slammed Park’s recent comments that the North’s obsession with nuclear weapons would bring about its own collapse and that the regime will “evaporate from the face of the Earth” if it ever uses a nuclear weapon.

The North has ramped up its rhetoric of a nuclear war over sanctions imposed by the United Nations on Pyongyang for its third nuclear test.

But despite the swipe, Park is sticking by her campaign vow to engage with the North and build more trust between the estranged neighbors, AP reports.

“North Korea’s nuclear programmes are unacceptable and we will respond thoroughly to provocations”, she said.
