No one guessed it right (but then, the person who I thought might get it, did not guess!), but the answer is behind the cut!!
Freshman year of high school, we went to see A Chorus Line at one of the local colleges (Franklin & Marshall for anyone who cares). I just L-O-V-E-D it and memorized all the lyrics to all the songs. Of course, the most popular of songs from A Chorus Line is "One". A line from that song is "She's uncommonly rare, very unique, peripatetic, poetic and chic." Say that 10 times fast! I think this might be the only time I've consciously heard the word used.
Also, I can hear the crickets here today! Where is/was everyone?
