Mine is my first name with the Japanese honorific -kun on the end. From what I have seen in anime (subs, not dubs, thank you), -kun is used as a familiar term, like in Fruits Basket when Tohru says "Kyo-kun" after he tells her not to call him Kyo-san, or when Shigure calls her Tohru-kun. And it flows better than Carol-chan. ::nya::
