Does Bloody Mary count? If so yes I did when I was in a child.
In elementary, we all believed and would try to get each other to say it in the boy's bathroom. Sometimes we'd shove someone in and held the door shut till they say it, usually we'd give up or a faculty shows up/
I'd say that counts. For me, it was both Bloody Mary and La Llorona.
We also had what you might call a local legend at the elementary school I attended. There was a busted up trailer at the far end of the school field and all the kids had this legend about how a witch-like monster lived in there and would snatch up children who dared to get too close. All the kids in the school never played near that trailer, and some said that, if you glanced over at the trailer, you might see the door creak open to a crack while a long, bony arm poked out and beckoned children to come to it. If you were within earshot, you'd hear a voice that seemed sweet, but with a tinge of a croaking gurgle, tell you that there's candy, toys and other fun things awaiting you in the trailer. When you got too close, the arm would shoot out (unnaturally long), grab you and pull you in. At that age, I had yet to even hear of Stephen King's It, but that scene in the recent movie where Pennywise's arm stretches out of the sewer and pulls Georgie in gave me flashbacks of the trailer lore. That local myth was there before I started that school, and from my siblings accounts, remained relevant afterwards.
