Backmasking
n.
the instinctive tendency to see someone as you knew them in their youth—a burned-in image of grass-stained knees, graffitied backpacks, or handfuls of birthday cake, superimposed on an adult with a mortgage, or children of their own.
In audio recording, backmasking is a technique wherein a sound is deliberately recorded backward, so it’s only intelligible when played in reverse.
