Friday Night Funkin' is an open-source rhythm game released in 2020, built around rap battles where the player character, Boyfriend, answers opponents with short beep and bop vocals instead of sung lyrics. Those beeps became one of the game's most recognisable sounds and were quickly clipped, remixed and shared across YouTube, TikTok and soundboards. This version adds an echo, a common fan edit that makes the short vocal feel bigger and more dramatic, which is why it keeps appearing in FNF memes and fan edits.
