Yield sign is a recent meme. It came about in the hallways of a humble middle school, when a student exclaimed at a running child "Yield sign!" and the child jumped and was taken by surprise. This was humorous to the surrounding group. As the day progressed, the student began to startle people by saying the word into other students' ears, and drawing the triangular symbol on people's papers. This student is notorious for electrical experiments, and once blew the circuits in the gymnasium and locker rooms by plugging in a makeshift device.
