Birth of Bronx cheer
Blowing a raspberry, strawberry or making a Bronx cheer is to make a noise signifying derision, real or feigned. It is made by placing the tongue between the lips and blowing to produce a sound similar to flatulence. In the terminology of phonetics, this sound can be described as an unvoiced linguolabial trill [r̼̊]. It is never used in human language phonemically (e.g., to be used as a building block of words), but the sound is widely used across human cultures.
The nomenclature varies by country. In the United States, Bronx cheer is sometimes used; otherwise, in the U.S. and in other English-speaking countries, it is known as a raspberry, rasp, or razz – the origin of which is an instance of rhyming slang, in which the non-rhyming part of a rhyming phrase is used as a synonym. In this case, "raspberry tart" rhymes with "fart". It was first recorded in 1890.
A raspberry pattern or the raspberry pattern represents the form that the mouth takes as it produces the noise similar to that created by flatulence, similar to that of gas as it is passed through the rectum.
In Internet English shorthand and on forums and blogs, the transcription "pbbbt" has come to be used to mean blowing a raspberry.
