I got the impression when I asked about SP texts a while back that there

Your student is referring to the "Bronx Cheer," or "rasberry" in some
circles. You can demonstrate it easily by looking at your monitor, then:
1) Stick your tongue part way through your lips, 2) keep your lips sealed
around your tongue, and; 3) blow air. The screen will "wiggle." The only
