Kenny McCormick is one of the four main boys in South Park, the long-running animated series known for its crude humour and Kenny's muffled voice from inside his orange parka. The three in the morning line taps into the wider online 3am challenge trend, where creators film creepy calls, dares and fake hauntings supposedly happening at the witching hour. Shared as a Russian-language soundboard clip, it spread among meme editors who wanted a recognisable character delivering a deadpan threat, and it survives because that mix of familiar cartoon comedy and late-night creepiness works in almost any short video.
