French: Avoir la moutarde qui monte au nez Literally: To have the mustard rising to the nose
Origin: American, documented in print as early as an 1869 Chicago Tribune article, describing someone extremely angry or exasperated. The image ties directly to real physiology: anger triggers dilated blood vessels and increased blood flow, producing a genuine rise in skin temperature most noticeable around the face and neck — precisely the area a shirt collar sits against. High, stiff, starched collars were standard formal menswear through much of the 19th and early 20th centuries, and a truly angry man in one would have felt that rising heat trapped uncomfortably close against his neck, giving the idiom a physically accurate basis rather than a purely invented metaphor.
