This reminds me of one of our high school capers. A bunch of us started using the phrase “Get Off Me” to excess. We would say it when someone stood too close, said something negative, etc.
Our calculus teacher did not like the phrase and BANNED it from being used in her classroom, so my friend climbed out on the balcony across the quadrangle from her classroom and wrote out “Get Off Me!” using masking tape.
It was taken down the next day, but we howled with laughter the rest of the year.
