One definition of origin:

For some odd reason, all the swear words in Quebec are sacred objects…Tabernac! being the favourite. Also popular swear words are Calice! (chalice) and Ciboire! (ciborium) Esti or L'hostie (host).


Os"tie, Stie. Québécois swear word meaning "The consecrated wafer; the host". Often used in a religious phrase, as in "'Stie d'tabernak!"

more info:

Before the 1960s the Québec identity was shaped by religion, in addition to language. The French-Canadians were almost entirely Roman Catholic. They were a priest-ridden, isolated, ignorant people, lacking a professional, commercial, or managerial class, except for the priests, kept in a sort of medieval limbo and economic inferiority by their dictators and owners, like the rest of Latin America.
