According to Pixiv comments, these three pictures are an Attack on Titan meme. I'm not familiar with the series, so idk what it could be referencing.

It's been at least a year or two out (or more?) since I've had any dealing with Shingeki no Kyojin so this slips me as well. The only kick meme I'm definitely aware of is Levi's on Eren Yeager in the military court.
