Friday Night Funkin' is an open source rhythm game first released in 2020 for a Ludum Dare jam and popularised on Newgrounds. Players battle as Boyfriend, who sings in beeps and bops to win a kiss from Girlfriend, the red dress character who sits on a speaker in most songs. Her short vocal sounds became popular with modders and editors because FNF has a huge modding community, and isolated character notes are reused to build fan songs, charts and meme edits long after the original weeks.
