NOUN archaic, historical

A coward, a villain; a person who breaks the law or a code of honour; an outlaw, a wretch.
In historical Germanic society, nīþ (Old Norse: níð Old English: nīþ, nīð; Old Dutch: nīth); was a term for a social stigma implying the loss of honour and the status of a villain. A person affected with the stigma is a nīðing (Old Norse: níðingr/ᚾᛁᚦᛁᚴᛦ, Old English: nīðing, nīðgæst, or Old High German: nidding),
A nithing pole sometimes normalized as nithstang or nidstang, was a pole used for cursing an enemy in Germanic pagan tradition.
I've known some truly faithless, betraying, oath-breaking nithings, one above all the rest.
May they experience the rightful curse and scorn upon them as such.
