Kilyle: The horns gesture is not the AMERICAN Sign Language gesture for Y. I don't know if it's in other sign languages, but the ASL one is thumb-and-pinky, all other fingers down. (Whether the American public knows this or not is a different matter.) Oh, and the horns gesture with the thumb out too (so only the middle two fingers are down) is ASL for "I Love You," although it's more used by those who don't sign and can be offensive to Deaf people, especially if you use it to imply "Hey, I can sign too" when you really can't.
- Actually, for the japanese it is not a warding gesture, it is a surprise gesture that even has its own name (I stumbled upon it when I researched some of the cultural phenomenons in Ranma, though I cannot remember the name of it).
