noun, masculine/bœf/plural: bœufs
ox; bullock, steer; beef; jam session; a police officer; a pig
“faire un bœuf” — to have a jam session
Inherited from Middle French bœuf, from Old French buef, boef, from Latin bovem (“ox”), from Proto-Italic *gʷōs, ultimately from Proto-Indo-European *gʷṓws (compare English cow). The music sense derives from the expression “faire un Bœuf”, after the Parisian cabaret-bar Le Bœuf sur le toit where jam sessions were held.
