Among Surrealist techniques exploiting the mystique of accident was a kind of collective collage of words or images called the cadavre exquis (exquisite corpse). Based on an old parlor game, it was played by several people, each of whom would write a phrase on a sheet of paper, fold the paper to conceal part of it, and pass it on to the next player for his contribution.
The technique got its name from results obtained in initial playing, "Le cadavre exquis boira le vin nouveau" (The exquisite corpse will drink the young wine). Other examples are: "The dormitory of friable little girls puts the odious box right" and "The Senegal oyster will eat the tricolor bread." These poetic fragments were felt to reveal what Nicolas Calas characterized as the "unconscious reality in the personality of the group" resulting from a process of what Ernst called "mental contagion."
