I consider skateboarding an art form a lifestyle and a sport. 'Action sport' would be the least offensive categorization.
If either player abandon the game by quitting the table in anger or in an otherwise offensive manner or by momentarily resigning the game or refuses to abide by the decision of the Umpire the game must be scored against him.
The thing is I don't believe in most of what's done. The amount of financial and imaginative energy that's put into mediocrity is just amazing which I find to be fundamentally offensive as a human being.
