The soccer culture:

There is no division between spring or winter sports in Spain so athletes usually practise their sport during all the year. And of course, the most famous sport is soccer. We call it "football", what has more sense, but you know, America is different.

Almost everyone played it and if not, basketball, what is the second most popular sport and people follow the American NBA for being more competitive.

A really typical habit is to invite your friends to your house, and while you are watching the game, you share some appetizers with they and everyone has a good time. When you mix this with beer, you will find the most most most most typical thing. People screaming and yelling for each play of the game and swearing really hard to the referee.

Sometimes even people starts fights for defend their team, because in Spain, this sport is almost a religion.
