Place it as the payoff at the end of a reveal, after the twist is shown, so the laugh lands as the final beat. Pair it with Oh My God just before the reveal for shock, then follow it with Emotional Damage to underline the defeat.

This four-second clip is Light Yagami's manic laugh as Kira from Death Note, a loud, rising HAHAHA that sounds triumphant and unhinged. It feels gleefully sinister, like a villain savouring a victory, and works as an instant signal that someone has just outsmarted everyone else in the room.
