She arched a brow. His brow arched in question. Arched, as in, brow raise in question, disbelief, sarcasm… or whatever other reason you would arch a brow. I don’t know, just ask Seven of Nine. She did it all the time! I use arched now instead of cocked because my dictionary doesn’t recognize ‘cocked’ as being a word. Go figure, because something can be cock-eyed, but not a brow. So now I use arched. And when I say I use it…. I mean ALL. THE. TIME. I probably go overboard, but since I can do it so well with my left brow, I figure every one of my characters should.
