Place it at the end of a spicy-food sequence, after Okay Let's Go sets up the dare and just before Nope signals the retreat, so the heat becomes the payoff rather than the opening joke.
Sobre este som
This is a sub-second vocal clip built around the words lava in the mouth, delivered in a warped, effects-heavy voice that sounds as if the speaker has just swallowed something burning. It lands as a sharp, funny jolt of pain and exaggeration, perfect for a sudden hot-food or too-spicy reaction, with the distortion doing most of the comic work.
