Place it right after the reveal or winning moment as the main reaction, then follow with a yaaaaaaaay cheer to turn a solo reaction into a group one. In a faster montage, lead in with a scream meme button and let this clip carry the final beat of the sequence.

This is a nearly four-second clip of Japanese YouTuber HIKAKIN letting out a loud, stretched scream of Tanoshii naaaa, his shout for how much fun he is having. It feels gleefully overexcited and infectiously happy, like pure joy pushed far past a normal reaction, which is why the burst hits as comedy rather than alarm.
