Let's see. HC stands for Hostile Creation, o'course. Honorary Aussie is back when the Aussie Thread was around and open to the public. All the aussies said that non-aussies that posted in the thread were considered Honorary Aussies, so I've had that in there since then. I think Ms. Pikmin was the only other one to do that, but I'm not sure.
The other one is a months-old quote from evil intentions, I think from the newbie thread.
All in all, it's an antiquated sig. Everything may or may not apply, but I think I'll leave that to memory now. I'll probably change my signature soon and reply back to this thread with the UPDATERED sig (with mp3 player and movie playback, of course).
