where did the term blowing raspberries come from
Blowing a raspberry Blowing a raspberry comes from the Cockney rhyming slang "raspberry tart" for "fart".[3][4] Rhyming slang was particularly used in British comedy to refer to things that would be unacceptable to a polite audience. The term "Bronx cheer" is ironic because it is not a cheer. It is used to show disapproval. The term may originate with crowd behavior at the stadium of the New York Yankee baseball team located in the Bronx NY.
