sex tuba

A threesome. of one boy and two girls.
One hole to bow in, one to play in, and a stick.

"Did you hear that Johnny plays the sex tuba in band."
"Mann, I'm going to join that class."

tuba sex orgy

The group of musicians in any marching band that play the sousaphone. The group can often be seen not practicing, getting drunk, or hitting on the twirler line. It should be noted that all members of the Tuba Sex Orgy are denoted "Bros," even female members.

I wish I could be a member of the Tuba Sex Orgy! Those bros are awesome!
