During anal sex, the receiver farts onto the giver's condom-wrapped penis, making a sound similar to that of a kazoo.
Guy 1: Dude, I was banging this chick in the butt and she totally kazooed on my wang.

Guy 2: Can you stop talking about girls when I am having sex with you?

A musical instrument that, when played, magically brings taunting, ridicule, verbal, and, in some cases, physical assault to the person playing it. The word "Kazoo" can also be used as another name for a tool, or person held in low regard.
"Spencer, please don't go into town with that kazoo of yours again - you know what happened the last time."
But Spencer heeded not his mother's warning - hapless kazoo that he was - and, with a sickening chortle, ziplocked the musical instrument inside his baby blue fanny-pack anyway.

It was the BEST PLAY EVER! Kazoo, is the story of Wren, a 13 year old girl. She’s an average girl, living a pretty normal life. She has a mom and loves to play her kazoo. She hangs out with her two best friends, Kaylee and Lily, in a treehouse that is their sanctuary. But then everything goes wrong – her mom dies, she has to move in with her aunt, her friends don’t understand what she’s going through and she loses her beloved kazoo. But with the help of a mysterious and funny stranger, Wren embarks on a journey to find her kazoo.

Kazoo is written in a storyteller style – there are eight actors who tell the story to the audience. All eight also become a character in the story.

Magic is woven throughout the story, from ghosts to talking rabbits to dangerous pythons. It’s a really fast-paced, fun and funny story with a lot of heart.

I was so glad that i was passing through Iowa when this show was being shown. I personally have a rough time with Grief as my parents got divorced when i was young and now my father is in jail for 3 years and he won't let me see him. I am 19, this showing that this show touches everybody. My 9 year old younger sister was crying by the end of the show and was saying that this was exactly what the world needs to see. Thank You Kazoo!
I just saw "Kazoo", it was an amazing show!

Kazoos are the holy instrument of the gods in the official religion Kazoodaism and one of the main subjects of the Kazoo Bible. It creates a buzzing sound when hummed into, and is played often by younger ones as their small hands and bad posture does not allow them to play other instruments like a violin, piano, trombone or drums (Which they can play, however they are terrible at it). Even though primarily children use it, it is not as simple as most people see it as. It, when played, increases your intelligence, and communicates directly with the Great Brett (Holy one of Kazoodaism). Kazoos became a popular internet trend when "You on Kazoo - Full Version" was uploaded to YouTube, a video sharing site. They showed the Great Brett, god, and the demigods, all of whom had special instruments of their own to help Brett create the world and universe. The Kazoo is also a symbol of life, and can be associated with the peace and love symbols (The circle split in four and the heart).

tl;dr The Kazoo is the greatest instrument and is the basis of the religion Kazoodaism.

What are you doing, Billy?

A kazoo is a magical instrument that makes wonderful sounds. Many people hate it and are annoyed by it, so that's just another reason you should get one! Actually I have four! Do not limit yourself! buy a million!!! Become God with the power of a kazoo.
Person 1: Woah! You got a kazoo?
Person 2: Yeah! So cool right?
Person 3: I hate that so much, never play it near me or i will rupture your spine.

A kazoo is a small, simple musical instrument consisting of a hollow pipe with a hole in it, over which is a thin covering that vibrates and adds a buzzing sound when the player sings or hums into the pipe.
Kenny had to admit that he was musically talentless. Even the Autoharp was beyond his limited capabilities. He knew then he had to persevere with the kazoo because it was his last chance to impress the ladies and perhaps lose his virginity before his 52nd birthday.
