Who cut the cheese?

At dinner tonight, my 6yo daughter was showing me a play doh toy that she called her cheese cutter. I looked at my Xennial husband and said, "please don't cut the cheese by me!" He and I were laughing while 6 and our 9yo daughter looked at us like we had 5 heads. They had no clue what we were taking about. I felt so old and dusty in that moment. When did people stop using this phrase??
