in the past week, i've seen two different people make this gesture: take the forefinger or pinkie and make a swipe at the tongue then proceed to swing that finger up and down once as if dinging a bell in one fluid motion. i forget the context of both instances... what does that mean? touche? good point? atta girl? oh, you sly, dry-witted fox?
"Score 1 point for you," as if you were making a hash mark on a chalk board; usually done when a person makes a correct and/or clever response to another person's question or comment. Nick
