– Definition: n. A type of local dialect.
– Used in a sentence: His discourse was punctuated by a patois rich in “I know, right?” “Wait. What?” and “Yeah, no…”
– Why: It’s a better (and more elegant and less judgey) label than “vulgar tongue.” Besides, I look forward to hearing people pronounce it “p’toyse” (as I did before I understood French usage).
