According to historian Eric Rabkin, the Canelos Indians believe that when they fart, the soul escapes the body along with the smell. “When in a group someone breaks wind, one of the rest will clap him on the back three times and say, ‘Uianza, uianza!’ The exact meaning of this word is unknown, but the person who farted is then obligated to prepare a uianza feast. (Alternatively, Rabkin says, the farter can discharge his obligation by giving the clapper three clay vessels of manioc beer.)
