About this sound
This is a roughly six-and-a-half-second baby cry run through heavy autotune, so the wail bends into a warped, almost musical sound. The pitch shifts make an ordinary cry feel exaggerated and a little sinister, which gives the clip a funny but unsettling edge. It is a meme edit rather than a line taken from a film, show or game.
