Clukr is one of the beat characters in Sprunki, the fan made Incredibox mod that spread through browser games and music videos online. In the mod each character adds a loop when placed, and Clukr contributes a bright metallic click. Players discovered that rapidly removing and replacing or clicking him creates a spam effect very different from his normal rhythm. Clips of that abuse started circulating in gameplay edits and meme compilations, where the short burst became shorthand for spamming, glitching and overdoing a simple action.
