Friday Night Funkin is a rhythm game that began as a Ludum Dare jam entry in 2020 and grew into a major Newgrounds hit, with players pressing arrow keys in time to songs during rap battles against opponents. Its short countdown and start cues became familiar to a wide online audience through gameplay videos, edits and memes, where the moment a song begins is instantly understood. This tiny intro clip is still reused because it packs that whole competitive setup into less than a second.
