low brass 

The dirtiest minded section in marching band. Low brass usually consists of tenor sax, trombone, bass clarinets, tuba and possibly french horn. Low brass is the closest family in all of band. We stick together and occasionally have orgies in the instrument storage room--which has the unique aroma of balls, dead virgins, and crushed dreams.

People in low brass usually love giving each other rusty trumpets and rusty trombones.

freeze the balls off a brass monkey 

A reference to extreme cold. According to the United States Navy Historical Center, this is a legend of the sea without historical justification. The center has researched this because of the questions it gets and says the term “brass monkey” and a vulgar reference to the effect of cold on the monkey’s extremities, appears to have originated in the book “Before the Mast” by C.A. Abbey published in 1857. It was said that it was so cold that it would “freeze the tail off a brass monkey.”. The Navy says there is no evidence that the phrase had anything to do with ships or ships with cannon balls.

The first taxi man George encountered in Brooklyn said, "It is cold fit to freeze the balls off a brass monkey."

Freeze the balls off a brass monkey 

Navy phrase for canon balls. The balls are placed in a round structure called a monkey. The plates had indentations to hold the balls on the bottom layer in place. The base was made of brass. When brass gets cold it contracts and the balls displaced.

It is so cold it would freeze the balls off a brass monkey.
