Hyoshigi have been used in traditional Japanese theatre for centuries, originally as a simple signalling tool made from two pieces of wood or bamboo struck together. In kabuki they mark the start of a performance, punctuate movement and draw the audience's focus to the stage. The accompanying yoooo style call echoes the spirited shouts heard from performers and audience members during climactic moments. Online, editors borrowed that unmistakable stage language as a meme cue, using the claps to turn ordinary entrances, announcements and plot twists into mock-epic kabuki-style moments.
