In OPA, we don't name the pledge class until initiation. The class is named based off the number of girls they had (eg. my pledge class was "9 Dancing Ladies"), and every girl is named off of that theme (eg. in my pledge class, we were all named after dances). The names don't really get used, especially since you're already a sister by the time you learn your own, but it's a cute thing for us to add to Rose Night.
