Nobody has pinned down where the Ddddddrrrrrala sound first appeared, and with only a couple of plays on record it looks like a user-made shock clip rather than a sample from a known show or game. Like the MLG air horn, it exists mainly as a loud punctuation mark for prank and meme edits, dropped without context because the noise itself is the joke. Unlike the short and tidy vine boom, this one is longer and messier, which makes it better suited to full-screen scares than quick reaction cuts. Its headphones warning has become part of the ritual.
