Blue Tuba

When the over excitable seaman preforms oral sex on the rest of the crew when they cross over the tropic of Capricorn or cancer while hiding in the dorade vents of a ship.

Hurry up! Davey from the Navy is manning the BLUE TUBA on the overnight watch tonight. You want to get in line early before the Boston Lockjaw gets tired and stops clenching.

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

contrabass tuba

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.

See the pic above.

Contras are the most badass instruments ever.

Wagner Tuba

A fucked-up musical instrument most frequently heard in the works of Richard Wagner and Anton Bruckner. Though capable of sounding quite beautiful, it usually sounds like shit and elicits dirty looks and sighs from the rest of the orchestra.

Musician #1: "What are we playing on tour in March?"

Musician #2: "Bruckner 8"

Musician #1: "Oh Fuck! Wagner Tubas!!!"

Whitewash Tuba

When a male ejaculates into the mouth of an obese female with enough force to cause her to expel flatus.

Dude 2: Yeah, one time I gave this girl a Whitewash Tuba.
