Does anyone not have an exclusive Russian
I like hooters.
What does your picture
It’s a slang term for the owl because of the sound they make. In english the sound is similar to our word “who” so an owl is sometimes referred to as a hooter.
Here’s another Hooter
And if you go into the 18+ section you will see more hooters 
And maybe even a kitty cat…
