I can explain! Rn in Japan they have this thing 壁ドン (kabedon, literally “wall thump”): when a dude slams his hand on the wall by a girl to keep her caged there with his arm. It’s supposed to be hella manly and sexy, but really people just meme the hell out of it, like the above.
the greatest variation i’ve ever seen of this is called “cicada block”, it’s where the dude has both hands and both feet on the wall
