One of the most blatant violations of the rules against touching saliva among other taboos is described by Dubois…in his  account of one of the “disgusting religious orgies” he so meticulously depicts. In these orgies, not only do men and women eat meat and drink alcoholic beverages, but they transgress the normal saliva prohibition. I cannot possibly improve upon Dubois’ vivid word picture: “In this orgy called sakti-puja, the pujari, or sacrificer who is generally a Brahman, first of all tastes the various kinds of meats and liquors himself, then gives the others permission to devour the rest. Men and women thereupon begin to eat greedily, the same piece of meat passing from mouth to mouth, each person taking a bite until it is finished. Then they start afresh on another joint, which they gnaw in the same manner, tearing the meat out of each other’s mouths. When all the meat has been consumed, intoxicating liquors are passed around, every one drinking without repugnance out of the same cup.
