What does Horsey mean?

You can see for yourself by hovering your mouse over the horsey emoticon.

I don't have a mouse.

Horsey is just something for little kids to make them happy. It has absolutely no meaning, hence kids get excited to post it.

Prove it.

@Rashell29
I always interpreted it as ambivalent, neither good or bad.

They say

The Tao that can be explained is not the Tao.

Likewise

The horsey that can be explained is not the horsey

It can also mean: I'm not particularly looking forward to dinner this evening.

I'm always using it as "We're having horse meat for dinner tonight".

Interesting statement of yours.
But there should also be many adults who still have a childlike mind.

In my opinion ... Horsey is a ludicrous chess figure, a jester for lichess.

Some like to horsey around with posts to joke about the subject.
Only a horsey would say something like that.
It a response to stuff a post with glee, when the other icons don't fit.
A he, ha, he, ha response, which is the sound of a donkey or horsey.

Is it a mascot?

I guess it's an expression of shock. The kind of shock you get when a knight fork your King and Queen.
