This sound is tied to Phone Guy from the original Five Nights at Freddy's, where his prerecorded nightly calls end with a distinct hang-up click. As FNAF clips spread through YouTube, TikTok and meme edits, the tiny phone disconnect became useful far beyond the game itself. It stays popular because it is instantly readable as a conversation ending, while still carrying the uneasy atmosphere fans associate with FNAF. It is often used alongside other recognizable FNAF sounds such as the FNAF Jumpscare Scream.
