FNF meaning in Computing ?

Friday Night Funkin' (often abbreviated to FNF) is an open-source donationware rhythm game first released in 2020 for a game jam. The game was developed by a team of four Newgrounds users, Cameron "Ninjamuffin99" Taylor, David "PhantomArcade" Brown, Isaac "kawaisprite" Garcia, and evilsk8r. The game shares some gameplay features with Dance Dance Revolution and PaRappa the Rapper and borrows aesthetic influences from Flash games. The game has been credited with driving users back to Newgrounds, a site whose popularity peaked in the early 2000s.

The game includes a roster generally comprising characters from external media on the Newgrounds site.

The game revolves around the player character, Boyfriend, who must defeat a variety of characters in singing and rapping contests in order to date his love interest, Girlfriend. Gameplay revolves around mimicking the opponent's notes with timed inputs while avoiding running out of health for the duration of the song.

The game was initially created for the Ludum Dare 47 game jam in October 2020. A full version backed on Kickstarter titled Friday Night Funkin': The Full Ass Game is planned for release in early 2022.
