It's a group mainly consisting of four members, there's others but in reality it's just about the core four. They try really really hard to show everyone that they are manly men and that they like boobs and bear and 'manly' things.
Recently there have been reports and whispers that the core four are completely and deeply closeted. Which when you think about their needs to show their masculinity. It probably isn't much of a stretch of the imagination.
