Place it directly after the unbelievable claim in your edit, then follow it with Bruh and later Emotional Damage to build the response in stages. Keep this clip first so the other sounds answer the same claim instead of starting a new joke.
Über diesen Sound
This is a roughly ten-second spoken clip built around the Colombian Spanish phrase “Cómo así ñerito,” delivered in a casual, questioning voice. The line lands as a mix of disbelief, teasing and playful confusion, the kind of reaction you use when a claim sounds too strange to take at face value. Its streetwise tone makes the doubt feel funny rather than hostile.
