tuba

A very big low brass instrument that is fucked by guys with GIANT dicks; also a instrument that a fat guy named Robbie rules.

The black guys got caught taking turns fucking the tuba during lunch break.

tuba

a type of urinal, the kind you might find in most male bathrooms. a tuba is the kind of urinal that is lower to the ground for midgets, and an inconveniance for tall people. it usually has the most bacteria on it, so cotton swabs can be used to test for this. occasionally mistaken for a musical instrument.

Abigail: Emily, we just tested the tuba for bacteria and man is there a lot!
Emily: What, you mean like a urinal?
Abigail: Yeah!

The tall man was at a disadvantage using the tuba urinal.

Tuba solo

A deep, low-pitched fart

"The last time I ate that much chili, I was doing tuba solos all night. My wife had to go sleep on the couch."

tuba circus

The cacophony of sound made by multiple noisy farts and/or bowel movements coming from multiple stalls in the mens bathroom.

I couldn't take a crap today at work; there was only one stall available in the mens bathroom and I didn't want to join the tuba circus.

tuba fart

The expelling of gas resulting in a low tone like that made by a tuba. Akin to a bugle fart but a much lower tone is produced when really pushing hard in order to hammer that sucker out.

My coworker just let out an enormous booming tuba fart that literally shook my desk.
