[Skooz]

I can think of one right now who behaves like a complete screaming banshee, attacking without warning or provocation. I ignore him/her/it.

I can think of one, too. I wonder if it's the same guy/gal/thing.

Could be, although there are so many to choose from lately!

(If I remember, I'll ping you next time I witness the banshee in action.)
