I had to check the source to get it: it's referencing a tiktok duo/reaction style video where the original video on the left is of a lady cooking something and the reaction video on the right is a different lady who is smiling whenever the cook is visible but stops smiling when the camera is focuses on just the food.

The woman cooking is also generally showing a lot of cleavage, so that's usually part of the art trend as well. Just not in this instance lol
