Raspberry is a slang term for the vibrating sound made
* when you stick your tongue out of your mouth with your
* lips closed and blow.  It is typically done when
* gloating or bragging.  Nowadays it's a pretty silly
* gesture, so it does not carry a harsh negative
* connotation.  It is generally used in a playful tone
* with friends.
