on the warpath, to be/go

To be infuriated enough to seek out the person or agency responsible. This Native American term was used quite literally by James Fenimore Cooper in The Deerslayer (1841) to describe a character who had never engaged in battle (“He has never been on a warpath”). By the end of the nineteenth century it was loosely used to describe anyone on an angry rampage.See also: go, on
