Place it immediately after the boast in your edit, as the reaction that punctures the moment, then follow it with Nelson's Ha-Ha for a second wave of mockery before returning to the speaker. Pair it with Damn Meme when the claim is especially overblown, letting that reaction land first and this clip answer it.

This nine-second Dutch voice clip delivers the phrase lekker belangrijk in a playful, exaggerated tone, stretching the idea of someone acting very important into a joke. It feels sarcastic and teasing rather than angry, like a friendly eye-roll at self-importance. The delivery makes the boast sound silly, so the listener hears mockery, warmth and amusement all at once.
