Beer pong has become quite popular in America. It has its own world series, which has its own official rules and regulations. These include protocols for dispute resolution, which might be heated. You can find examples of extreme beer pong on YouTube if you’ve never seen this yourself.
Most beer pong matches are not serious competitive affairs and, if the participants are drinking, their recall of events the next day may not be complete anyway. There are inflatable beer pong tables as well, so you can use one practically anywhere. Tables range from 7 to 8 feet in length.
