I finally got around to reading your comic. I just got started, so there isn't much I can say about it yet, but...
The second I saw this I started laughing inside because this is a nickname A.J. often gives to Donnie. (Minus the The) I realize thus far she's only really said it once, but it'll pop up some many times as the series continues. So although I've no feedback yet, I can safely say you have something in there I will never forget.
