getting pearled?

[dukedg]

Someone correct me if I'm wrong, but I thought getting pearled was the equivalent of getting pinned, but by a non-affiliated boyfriend. At least, this was the case at Duke. Thus, it is the equivalent to the seriousness of getting pinned, which at Duke was "engaged to be engaged." It was always a single pearl when I saw it done (similar to the look of a lavalier, I guess).
