An irritated state. When having a fantod, people talk faster and move their hands around more often then normal. Often happens to those who worry about college and/ or are doing too many extracuricular activities.
But by and by, sure enough, I catched a glimpse of fire away through the trees. I went for it, cautious and slow. By and by I was close enough to have a look, and there laid a man on the ground. It most give me the fantods. --Mark Twain, Huckleberry Finn
