The laugh belongs to Kim Seok-jin, known as Jin, the oldest member of South Korean group BTS. Fans nicknamed it the windshield wiper laugh because its squeaky, rhythmic sound resembles a wiper clearing a car window. Clips of Jin laughing during interviews, variety shows and behind the scenes videos were compiled by fans and shared widely online. The nickname stuck and the sound became a standalone reaction clip, used far beyond the fandom to mark moments that are unexpectedly and helplessly funny.
