On KidzNet, several users (Queeny, KnightStar, etc) have "crazy modes" when things they like are mentioned. Here are things that can activate mine (LOLZ, among other things, so if you mention them expect all caps and countless references to said fandom):
The Bleach anime, or any mention of any character, dead or alive, male or female, human or Shinigami or Quincy or Arrancar or Hollow or Fullbringer, good or evil, etc. Or if you post a photo, news relating, a picture that has a super tinny Bleach reference, a game relating, ANYTHING. You are warned.
2. ANIME IN GENERAL.
If it's an anime I recognize, expect GH MODE to be activated.
3. HATE SPEECH OR ENCOURAGEMENT OF ANIME
Either one of these, rather you hate it or love it, will activate me.
4. HARRY POTTER.
Yep, Harry Potter.
6. RESIDENT EVIL.
Less likely to activate, but still likely
7. FANCY PET RATS.
Now you know. Have fun!
