a barracuda pike is a submerged pike position at 45 degrees or less. If you don't know synchro terminology it means that your legs are perpendicular to the surface of the water with legs straight and toes just under the surface. Your body should be bent up towards your legs as far as possible with the goal to get your chest to your knees and your hands should be sculling just behind your heels. The vertical alingment (what should be straight up and down) is toes, ankles, knees, hips.
