Particularly hep readers will have noted that all the phrases are names of tracks playable in Guitar Hero, somewhat of an obsession at the time. At one point, there were three or four of us who could go back and forth, reeling off names of songs. A popular version (particularly online in text-based chat clients) was Guitar Hero Association: the next song title needs to be related to the previous one, either in subject matter, band, album, or name. This is the point at which most normal people would scoff and laugh. I would, however, caution you that it is significantly more difficult than it looks, and makes for an excellent way to pass time.
