That's the name of a YouTube channel with more than 77,000 videos. Dozens more are uploaded every day. And almost all of them look like this:
They're all 11 seconds long. They have no description, no explanation, and if anyone knows where they come from or what they mean, they're not talking.
Seven months ago, Webdriver Torso burst on the scene with its first quixotic videos. Back then, all of them were titled "aqua." As you can see, Webdriver Torso hasn't exactly changed much over the last 77,000 videos.

If you type "Webdriver Torso" into the YouTube search bar, you'll see this:
