If you're asking for something deep meaning, there's non. If you want some hard interpretation of it and looking way into it here it is: In a religious sense, when someone can be born again through baptism. "Out of Water" might be a reference of someone being born into the life of the forums through the depths of the water (baptism) which is why it's probably a low ranking title.
Man these are awesome. I have been on this forum for a while now but don't really post enough to get these titles. Maybe i'll go to find some help section and help out all the newbs, since I have been playing Minecraft for years now.
