We used to play a game called “buck buck”. Consisted of 2 teams…one guy would lean against a wall. Next guy would bend over and put his shoulder into the 1st guys groin area (not what you’re thinking either) Each other guy would then bend over and place their head between the legs of the guy in front of him so all that was exposed really were the guys backs. Other team would then one by one run and jump on the backs of the other team. If the team jumping could not get all their members on or if a guy fell off or his foot touched the ground after he jumped on, they lose. If the down team caved in they lost and had to assume the same position for another round. Once all of the 2nd team had jumped on and no one caved in, one of the members of the top team would yell out, “Buck buck how many fingers up?” One of the bottom guys had to guess how many fingers was being held up. If they were wrong they were down again for another back pounding. If they guessed correct, the teams changes positions for the next game. It could be a very rough game. We played this in McKeesport, PA.
