Mr. Fun Computer is a character from Sprunki, the fan-made horror spin on the Incredibox music-mixing formula, known for its normal Phase 1 and corrupted Phase 2 designs. In Phase 2 he is depicted as glitchy and menacing, often paired with distorted whispering. Clips of his fed-up outburst spread through Sprunki gameplay videos, shorts and meme edits, where players highlight the moment the cheerful computer persona cracks. Soundboard uploads kept it circulating as a shorthand for digital frustration, and it remains popular with horror-meme editors.
