What Gon from Hunter x Hunter says in his Nen attack Jajanken. It is basically a rock paper scissors attack. There are three different attacks (rock, paper, and scissors). This attack (rock) is his strongest. If you want for information about his Nen attack, watch the anime. It's one of the best shounen animes and one the best in general.
