Put it just before the reveal in a prank edit, after a short typing sequence, then follow it with a shocked reaction once the fake message lands. A bass-boosted Discord call works as a follow-up for the punchline.
About this sound
At about half a second long, this clip is the familiar Discord ping, a crisp alert that cuts through a quiet room. It sparks a quick jolt of curiosity and the reflex to glance at a phone, half amused and half caught out. It originated as the notification sound in Discord, the messaging and voice chat platform used by gamers, communities and streamers.
