Who was pitching and who was catching?
A technique of checking a girls ass out by dropping a simple item (i.e. a pencil, hat, gum wrapper, etc.) and having her to pick it up by bending over with her butt faced towards you. This trick is very hard to pull off because you have to be very convincing.
Boy sees the school slut (ahot girl) walk by, and drops pencil, close enough to her. Girl stops, bends over, and boy gets a good glimpse of her butt. Girl hands him pencil, and walks off suspecting nothing. Boy smiles to himself, a champion of pitching, looking for more bait.
