Put it after the sibling fail is shown, then follow it with goofy ahh sounds for a bigger reaction, and close with bruh when the joke lands flat in front of friends.
About this sound
This 32-second meme clip plays on the goofy ahh brother joke, using an over-the-top, playful delivery to turn an ordinary sibling moment into something deliberately silly. It feels light-hearted and ridiculous, the kind of sound that makes a dumb joke land harder because it commits fully to the bit.
