Origin: Variant of obsolete fist
Origin: , short for fisting dog
Origin: , from Middle English fisting, a blowing, breaking wind
Origin: , from Old English fīsting; see pezd- in Indo-European roots. Regional Note: Feist, also fice, is one of several regional terms for a small mixed-breed dog. Used throughout the Midland and Southern states, feist connotes a snappy, nervous, belligerent little dog—hence the derived adjective feisty, meaning “touchy, quarrelsome, or spirited,” applicable to animals and to people. Although feist remains a regional word, feisty has now entered standard usage throughout the United States.
