Cicada Block, known as “Semi-Don” (Japanese: 蝉ドン, lit. Cicada Bam) in Japan, is the physical act of trapping someone in a corner by pressing one’s hands and feet against the adjacent walls to form a one-man barricade, mimicking a perched cicada insect. The block was first introduced on Twitter and later spread to the Japanese artist community pixiv and Tumblr, where it spawned a series of crossover fanart featuring other well-known video game and anime characters.
