noun, masculine/mo d‿e.ɡliz/plural: mots d'église
curse word, specifically one derived from a religious term
“J’ai cité Manu disant « crisse », mais j’en ai biffé quelques-uns. Sachez que Manu est en t**** contre le système et il ponctue ses diatribes de mots d’église.” — I've quoted Manu saying crisse, but I erased some others. The point is that Manu is f****** furious with the system, and he punctuates his diatribes with curse words.
Synonyms: sacre
Literally, "church word," since Quebec swearing (sacre) is based on religious terms.
