Griffin is Chessie’s brother, not her sister. But he looks a little girly-ish, which is why I said he’s bishy.
Bishy is short for bishounen, and is a word that comes from the japanese anime and manga, where a lot of the guys are, er… girly. It means something like girly-boy, or pretty-boy. But you don’t usually see guys in real life that look the way anime bishounen look. I think that Griffin does though, kinda.
Is all explained?
P.S. I like bishies, so calling him one is meant as a compliment! Though I suppose some guys probably wouldn’t take it that way…
