Sometimes just to mess with others fishing around me ill jerk my line REALLY hard and yell "Walleye!!!!!" and reel up fast as possible, Then just re cast like nothing happened. Dumb I know, but the looks are priceless.
Another one a friend and i started a long time ago was just simply "Natural Presentation" when we would mess up and cast all the way on the bank, or when we would cast over a tree limb on accident.
