Wanting to purchase a hand-held grater, she went to a small local hardware shop which was run by two elderly ladies.
Before going any further I will tell you that the French term for “grater” is “râpe à carrottes” (pronounced “RAP”).
So, not remembering what the English word was for this kitchen accessory, she decided to describe the item instead.
So, she made energetic back-and-forth gestures with one hand, pretending she was grating a carrot, while holding the imaginary grater with the other hand, and said in front the two horrified ladies:
“You know, something to rape carrots”.
