RackaRacka is an Australian YouTube channel created and run by twin filmmaker brothers Daniel "Danny" and Michael Philippou, based in Los Angeles, California (originally from Adelaide, South Australia). The channel is known for its intense live action horror comedy videos, as well as for their videos that satirise McDonald's mascot Ronald McDonald as a high-pitched speaking psychopathic killer clown. Most of its videos have been known for containing excessive amounts of graphic violence, vulgarity and sexual content, resulting in a handful of them being flagged on YouTube due to controversy as well as being banned in several countries.
