Dialect from the New York area, a medium-pitched warbled emitted from the rear poop passage, usually associated with the emission of shit juice.

Bronx Cheer is a term associated with a similar word from the New York dialect, Bronx Bombers - a word commonly misunderstood to refer to the proverbial team's hitting prowess, it is now known that both terms originate with a regrettable roadtrip night during which the Pinstripers spent binging on beans and broccoli.

The home team, none other than the Chowds, was so overcome with the super nauseous naus that contributed immediately to the Yanks 8-1 win the next day, as well as an immediate need for team-wide uniform pant replacements.

The next time the commie-boots visited the Babe's house, Yankee fans greeted them with a chorus of orally-produced "Bronx Cheers" complete with dip-juice to simulate the events of the road trip prior.

A sign of contempt, usually when you
stick your tongue between your lips,
and you blow though them, resulting
in a loud, blubbering, and flatulent
noise. Also called a raspberry
(definitions 2 and 3).
My coworker from my old job was
such a loser. I said to my friend
online that he deserves a loud,
rousing good cheer...

... a Bronx cheer.

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.
