My grandma (she’s 98) says “petrol” instead of gasoline, “icebox” for fridge, “automobile” (with the accent on the “mo”) for car.
Mom uses the word “oleo”. I hate that.
My house was built in 1914, and one of our rooms is officially called the “southeast parlor” when we’re in a pretentious mood. Otherwise, we call it “the kids’ play room”.
