Chance-medley

chans′-med-li, n. homicide justifiable because done in the hot blood caused by an unprovoked a ault—the word has no reference to homicide by accident: inadvertency. [O. Fr. chance medlée , mingled chance. 'From the fact that medley is also a noun, and chance-medley a po ible combination in the sense of "fortuitous medley," the meaning has often been mistaken' (Dr Murray).]
