Why are my guy friends crying only when they are drunk?

So some of my friends they don't cry unless they are drunk and when they are not drunk they don't cry at all. Why? I know and see people who act crazy or more aggressive when they are drunk but what explains the drunk crying? I think anyone can cry when they need to.
