Place it at the end of a build-up, after a Game Show Buzzer sets up the wrong answer, then follow it with Bruh for a deadpan reaction to the fallout.
About this sound
This is the longer alternative version of the WeToFo Ka-Boom blast, an extended explosion sound that stretches the impact out for about nine seconds instead of ending quickly. It feels big, sudden and playful, like a cartoon-sized detonation made for a punchline rather than a serious scene. It works best when the joke needs room to breathe before the payoff lands.
