World cup: Why do people support teams they have no relation or connection to?

An example, for the world cup, i was watchnig a video on youtube ( i was going to post the link but couldn't find it) and it showed how the Bangladeshi were either cheering for Argentina or Brazil to win the world cup, and the nation was divided between those two countries. Also, personally, i have to friends from Bangladesh, they are cousins, one is supporting Argentina and the other Brazil. They really have little connection to these South American countries yet they cheer for them. There's nothing wrong with it, but i asked one of them why they were supporting Argentina, and she said because the men were hotter. that's a stupdi reason.
