Grab a blender and a load of ice. Fill the blender with shaved ice and then add a good amount of coconut rum and spiced rum, with about a shot of triple sec (depending on what you like), top it all off with some good old orange juice and blend until its a slushy consistency. Its very strong, but has a fun tropical flavor and can be served as a punch. If you like, add a dash of lime or lemon juice to make it more sour.
