In high school, I once heard a student say, "I KHTRed this test." Translation: The frequency of our contemporary hit radio station in the late '80s, KHTR, was 103.3 FM, rounded down to 103 on the air. The student had gotten 100% plus three extra credit points.
Given that terrestrial radio is an afterthought, at best, to most kids, I'd be surprised if any student would tie a test score in with a radio frequency today.
