This is a short, deep bass boom lasting just over a second, with no voice, just a heavy low-end impact that drops and fades fast. It feels sudden, dramatic and a little ridiculous, like a fail getting its own explosion. It comes from the Vine Boom meme, where the sound punctuated awkward and disastrous moments in short videos.
