Maybe.
Good reporting, Stephra!

--- I have no idea what it means either but, that video 8-o is, well, slightly
bizarre! Cool song but, otherwise, over my pay grade.
But, if correct, that would mean, some people might have not been 'hearting' me but, hitting me up for
cash - er, 'lion $' or just making very adorable smilies? It is a cute smiley - just the urban legend, as urban legends go...hmmm.... yet, another one of life's mysteries, possibly. (it'd make more sense if the lion had Visa or Mastercard, like the rest of us, loving to 'overuse' these things...can't get enough e-
juice!

)
Thanks for sharing - We're up to 2 new smiley faces & a heart, now!!!
Maybe they were trying to make the lion face smilie:
>:3
For reference:
Urban Dictionary: lion cash
I don't claim to understand it. I'm only reporting.
