Also known as " blowing a raspberry" or "a raspberry". It is made by placing the tongue between the lips, or alternately placing the lips against any area of skin, and blowing. It is meant to replicate a fart and is a sign of derision. The term "Bronx cheer" dates back to the 1920s to signify this sound. The other definitions are historically incorrect if they do not mention this sound.
