A siren whistle sound effect created by Hanna-Barbera that is used in almost every freaking animated show. It was used regularly in their productions before the studio made their library royalty-free. That's when the sound spread to other studios. Nowadays, people are getting tired of hearing the sound especially when it's used in the more recent animated shows and films, and even some video games made use of it!
This sound is considered a mentally ill person's worst nightmare (or perhaps the entire Hanna-Barbera sound library). For some, they're just uncomfortable to hear, and for some, they pose a real health concern. Made especially worse if you have autism or Asperger's. If you hear just one sound or even this, you will have a heart attack or ligma, or a mental breakdown that could land you with PTSD. Better watch yourself when you watch YouTube because both can kill. But also beware of the sound being played in public. If possible, wear headphones with music turned up to max volume.

I wanted to play Pokémon Legends: Arceus on my Nintendo Switch, but I can't because it has that stupid big whistle zing out sound that nobody likes. Thank God for Sound Effects Wiki who helps me make informed decisions when I choose whatever games or shows I want to play or watch. When I'm out in public, I'll always listen to the soundtrack to the newest Touhou game to ensure that this sound and others never reach my ears.

Talking complete and utter nonsense. When something someone is saying is so completely and totally inaccurate and worthless that its value equates roughly to a whistling noise emanating from the anal area.
Phil said he's going to run for President next year!
Yeah right, he's just whistling through his ass!
Do I know what I'm talking about here or am I just whistling through my ass?

He swore up and down he wasn't racist, and got all pissed about it, even after saying he just couldn't stand working with black people anymore. I guess he just can't hear dog whistle racism.

This is a great party. Where's John at?
He's up at the school whistling.
John is an email butt-whistle
