Alternative forms

 * köld eru kvennaráð

Etymology
From the 13th-century Njáls saga, literally "the schemes of women are cold/cruel". Spoken by Flosi to Hildigunnur after she egged him on to avenge Höskuldur's death – she had done so by placing Höskuldur's blood-filled cloak on Flosi.

Proverb

 * 1) women sure can be cold and calculating; women sure can plot cruel schemes

Usage notes
Said to indicate that one is shocked and/or impressed after hearing of a particularly cruel scheme by a woman. A relatively common saying in modern Icelandic (compare for example the English saying ). The saying does not have disparaging undertones, instead it is more of a cultural reference.
