乳揺れ錯視
An [[optical illusion]] in which an image, when overlaid with a certain semi-transparent template, will appear to move when the whole image is shaken.

The illusion became a Twitter [[meme]] in September 2019. Images with this template are intended to be viewed on a smartphone and shaken to cause part of the image to bounce or jiggle.
