OK, I'm old and admit to not knowing a lot about this crap. Smiles, thumbs up, thumbs down, drunk etc are all pretty obvious, but where the hell in a post would you use a "dancing lock" Emoji? What does that convey?
Nyquist was a dancing lock for the Derby and will likely win the Preakness, but there is no way he will win the Belmont. But, I'm not an emoji kind of guy.
Since it looks like a Happy Dancing Lock I would say it means: I just booked my next trip and my final plans are all Locked up!
I have a new phone woth a bunch of emojis, I actually get a real kick out of them. Weird thing about my phone emojis is some change when I send them. I have a good friend who restores vintage VW's and there is perfect old VW bus emoji but when I send it, it morphs in to a firetruck. There is also a disco dancer dude who morphs in to a salsa dancer woman, no idea why. No facebook etc. for me either............
The dancing lock kind of reminds me of the Coyote Moon slot video on Youtube All of the spins were losers and after each and every spin, the dancing Ancient spirit(the bonus symbol who looks down at the ground while dancing) came on the screen dancing while the screen said "Congratulations, you win 0 credits!" LOL A Youtube poster posted,"WTF?" But I found it ROTFF(Rolling on the floor funny) LOL!
