"Black-eyed teeth" is a riddle made up by geyser after listening to Drifting by Recoil.

Unless mentioned otherwise, I=me=geyser in the stuff below.

The Riddle

Many riddles force people to think or speak of familiar things in rather unconventional ways.

There are unfair/unsolvable riddles, from elephant jokes to What has it got in its pocketses?

Even in the case of fair riddles, the fairness is usually the result of some sort of convention.

In that sense, I can not guarantee that the riddle I pose is fair. At least not on my own.

For my part, I took it as an actual, fair riddle while I was the one solving it... of course.

Then one day the answer dawned upon me, and I took the solution as fair enough.

(a friend was around at that very moment and acknowledged the solution)

Then I offered it to Guido as a mere "twisted mind synchronization test".

Finally, I became confident in the riddle's fairness and spread it around.

So far, only a couple of people have come up with the correct answer.

My sister thought the riddle was reasonably fair, and Guido didn't ^_^

LastmanSAC answered correctly but didn't comment on the fairness...

I will try to make sure this page is not frustratingly misleading.

I came across Drifting on YouTube after becoming aware of Recoil (thanks to Neo).; It is the first single from Recoil's album Unsound Methods and it has an official video.
Lyrics: http://www.rogerwatersonline.com/Artists_r/recoil_lyrics/drifting.html (dead link); (those are for the longer album version)
Note: Although I liked the video very much, it has nothing to do with the Riddle.; Just like the music, it has had no other function than to convey the Words.
Also note: The riddle is enclosed in a longer phrase in the song's actual lyrics:; "with your wild, with your sweet, with your cold, black-eyed teeth"; (or maybe just the shorter phrase "with your cold, black-eyed teeth"); I decided to reduce the riddle to the key terms "black-eyed teeth".; I might have complemented them with a few extra words, but didn't.; Instead I chose to provide additional hints as detailed below.
