This types of curses are very common in most Romantic languages -- they're used so commonly that many people might not even consider the origins...
I think some people on this thread are ascribing a particular moral deficit to French culture which isn't really fair...
The below article is pretty interesting in a sociological sense, but pretty sad from a Catholic point-of-view. There are ten major things God clearly told us not to do. Only ten. Is respecting God, and things related to God, that hard to understand?
In French-Speaking Canada, the Sacred is Also Profane(Source: http://www.religionnewsblog.com/16742/in-french-speaking-canada-the-sacred-is-also-profane) MONTREAL — “Oh, tabernacle!” The man swore in French as a car splashed through a puddle, sending water onto his pants. He could never be quoted in the papers here. It is too profane.
So are other angry oaths that sound innocuous in English: chalice, host, baptism. In French-speaking Quebec, swearing sounds like an inventory being taken at a church.
English-speaking Canadians use profanities that would be well understood in the United States, many of them scatological or sexual terms. But the Quebecois prefer to turn to religion when they are mad. They adopt commonplace Catholic terms — and often creative permutations of them — for swearing.
In doing so, their oaths speak volumes about the history of this French province.
“When you get mad, you look for words that attack what represses you,” said Louise Lamarre, a Montreal cinematographer who must tread lightly around the language, depending on whether her films are in French or English. “In America, you are so Puritan that the swearing is mostly about sex. Here, since we were repressed so long by the church, people use religious terms.”
And the words that are shocking in English — including the slang for intercourse — are so mild in Quebecois French they appear routinely in the media. But not church terms.
“You swear about things that are taboo,” said Andre’ Lapierre, a professor of linguistics at the University of Ottawa. In the United States, “it is not appropriate to talk about sex or scatological subjects, so that is what you use in your curse words. The f-word is a perfect example.
In Canadian French, you have none of the sexual aspects. So what do you replace it with? You replace it with religion. If you are going to use a taboo word, it would be anything related to the cult, to Christ, the Communion wafer, Jesus Christ, vestments, and elements of the altar like tabernacle. There’s quite a few of them.”
Visitors from France are dumbfounded at that use of French, said Lamarre. “But that’s because they got away from domination of the church a long time ago. They cut off the head of the king really early. We didn’t do that.”
The Catholic Church was overwhelmingly dominant in Quebec from early in the province’s history — England’s King George III gave the French Catholic clergy enormous power in 1774, in part to counter the growing American insurgency to the south. In the “Quiet Revolution” of the 1960s, Quebecers rebelled. They “just stopped going to church one Sunday,” as Lamarre put it.
The swearwords have persisted even though church attendance has plummeted in the past 40 years. Because of that drop, “when the young kids on the street are swearing, they don’t even know what they are swearing about,” mused Monsignor Francis Coyle, pastor of St. Patrick’s Basilica in Montreal. “They’re baptized in church, and that’s about it.”
Last spring, the Montreal Archdiocese commissioned an advertising campaign that erected large billboards in the city intended to shock and educate. Each billboard featured a word like “tabernacle” or “chalice” — startling swearwords on the street — and offered the correct dictionary definition for the religious term. Such as: “Tabernacle — small cupboard locked by key in the middle of the altar” containing the sacred goblet.
“The point was to try to get people not to use the terms too glibly,” Coyle said.
The campaign ended, but Lapierre said Quebecers continue to use the words in highly inventive ways — as expletives, interjections, verbs, adverbs and nouns. One could say, for example, “You Christ that guy,” to mean throwing a person violently. “I don’t know any other language that does that so well,” he said.
The French here also modify the oaths into non-words, depending on the level of politeness desired. The word “bapteme” — baptism — is used as a strong oath, but a modification, “bateche,” is milder. The sacramental wafer, a “host” in English and “hostie” in French, can be watered down to just the sound “sst” in polite company. “Tabernacle” can become just “tabar” to avoid too much offense.
The oaths are so ingrained that one cannot converse fluently without them, said Lapierre. “I teach them in my class.”
