real easy. after scoring a goal, hit either X Y B A. also hit the RS while pressing the LT (for riding stick) or RT(one knee) to a fist pump

This is a really easy achievement. All you have to do is right after you have scored a goal is move your RS to fist pump, or press any of your controllers buttons even triggers for any of the pre-made celebrations. You can also combine the fist pump along with the pre-made celebrations just to mix things up.
