Why, "flicking butterflies?"
My fiancé's sense of humor is very tongue-in-cheek, and sometimes I'm too busy laughing to come up with a witty response, so I flip him the bird finger. One day, it happened so often that we joked about having to tell our hypothetical children it meant something else, such as, "I'm flicking butterflies at you." I started using it, even when we aren't around children, and I thought I'd use it here, too.

Got a question?
Post to the comments, and I may add it here.
