Ornographic Mysteries of the Googleverse

Sometimes I do not understand the internet.

I did a Google search for "Bulgarian juice" and got porn sites. What I don't understand is why many porn sites have random strings of words attached that look like Dadaist poetry. "Lawless member computerize the accomplishable black bike week booty clips orbs with Bulgarian juice" is what one hit said. Is it to lure in businessmen who are legitimately working, maybe needing to type "computerize" into Google for a business-related search, and then -- whammo! -- they are lured into looking at porn?

But that doesn't explain "black bike week."

(I didn't want to put the P on "ornographic" in the title of my post in case it should lead to spam. "Ornographic" probably means something like "of the imagery of birds" but do not be deceived.)
