A nationwide event that is held during the Christmas season which hundred of tuba player gather to play Christmas carols.

A loud fart on the toilet that usually results in a highly accelerated poop shooting into the toilet.

Much like a rusty trumpet, only with a much larger partner.

sassy tuba can be defined as sucking a shit covered penis whilst reaching around and fisting the asshole of the recipient.

Extended meat flaps on a large woman. Particularly useful in describing a queefing woman.

When you take a shit into a funnel that runs into a girls mouth, which she then proceeds to puke the poop into the entrance of a tuba. You then play the tuba so that the liquids squirt out into the girls mouth. She then swallows the mixture and eventually shits it out into a bucket, where you then make her cum and squirt into the bucket. You piss into the bucket and pour it into a water gun. You go to a cemetery, dig up a body from a grave, and let it dry in the sun for 24 hours. You go back to the body and shoot the liquids into their urethra. You then piss into the dead bodies mouth and force water down their throat, preferably about a gallon. You wait for the liquids to proceed into the bladder. Next, you fill the vagina of the dead body with shit and cum. You tip the body upside down for 10 seconds, and then you lay it down. You put your mouth over the urethra, and the girl puts her mouth over the vagina; if there is not enough room, just have one person put their mouth over both parts. Take two anvils and have two friends drop them directly on the stomach and bladder. The contents of the carcus will project into you and the girls mouths, giving you an instant, pleasurable taste. You have completed the tuba slurp.

A tuba designed for marching that resembles a concert tuba in shape but is carried on the left shoulder. They usually weigh between 35 and 55 pounds.

The visual advantage for such a tuba on the field is that it can be held in carry (held vertically in front of the person) and in various other positions.

They are called Contras for short.
