Bonobono is a Japanese manga series created by Mikio Igarashi, centered on a young sea otter and his animal friends. It later received anime adaptations and became especially recognizable in Korean online culture through reaction images and edited clips. The label 보노보노땀 translates roughly to “Bonobono sweat,” referring to the character’s anxious sweating expression. The sound remains useful because its short, subdued delivery turns hesitation and discomfort into an instantly readable comic reaction without overwhelming the scene.
