Okay. Me and my friends (Eisei Pika-ki and her sister, strangerthanthou) were watching Yu Yu Hakusho, the movie Poltergeist Report, when strangerthanthou suddenly came up with a nickname for Hiei, due to the way he leaps from building or trees. it was Bunny Rabbit (the nickname). I'm so absolutely obsessed with Hiei, that I have adapted to the nickname; BunBun, instead. Also, strangerthanthou came up with more nicknames for the other characters.

Yusuke: Gun Gun
Kurama: Girly-boy (Eisei pika-ki doesn't like this because she claimed Kurama and Youko as hers.)
Hiei: Bunny Rabbit (BunBun)
Kuwabara:Idgit (Idiot and Midget)
Yakumo: Shika Boom (he's the king of the netherworld ^_^!)

Is that not funny?

I don't have any stories, yet... (Sorry)
