Any game where you kick a ball is called football. The different types of football are called "codes". All in all, there are six different codes of football. 1. Gridiron, aka American football (too complicated) 2. Rugby union (the game payed in heaven) 3. Rugby league (for thugs) 4. Gaelic (always a party) 5. Australian rules (very athletic) 6. Association football, aka soccer. (for the dumb)

I take it you're not a big fan of the game? :P

i believe there are some cultural and historical problems which i don't understand behind this question.However after surfing the internet,i got some answers.As we know,football originated in soccer.In 1923 on a football(i mean soccer) game ,a accidental missed kick make the players very disappointing. As a result,a player pick up a ball and ran ,which broke the rule.Afterwards ,this behavior inspired the people that this can develop to a new sport.And because Rugby came from football ,so name haven't change since then.
