That's a Juggernaut reward item from one of their St. Patrick's Day items. You probably visited someone's personal space where they had the gifting item out somewhere(LMO is granted for being in the same space).
You probably also had reward lag so the item didn't appear until you relogged later.
You're welcome Hinata I know what they are so well because the sparklers, used with a little creativity, are easy to spread smiles with. I was pleasantly surprised when Juggernaut offered a reskinned version as a gift for friends.
Sparklers were 99cents and came out around the same time as those butthuggers... That combo was pretty much our seasonal outfit good times^^
