Waldy is a girl's name that comes from Waldina but is a diminutive. I think only one in 500 people is called Waldy in the world, it's a not-so-nice name to be honest.
Waldy is a hot, very beautiful and intelligent girl who likes to fight and if she sees that you are very weak for her always in some way or another she will seek to mess with you, it is just a matter of exercising command to fall in love with her.
Boy 1: Waldy is angry all the time
Boy 2: No, you make her angry.
