Not sure exactly what this is, but it looks cool.
FanHouse UK describes it as:
Apparently the objective is for a team to defend their pole for two (some say three) minutes. If the pole tips 30 degrees or more for three seconds the defending team loses.

“The game seems to have been first played in 1954-55. The pole doesn’t have to hit the ground completely. It only had to go down 45 degrees until 1973 when the rules were changed to force teams to drop it to a 30 degree angle. One can only assume the losing team has to commit seppuku in front of the spectators. There is no honor in losing. Forgiveness please!”
