Scientists have finally explained why all of your best nights out with your buddies involved drinking 15 beers.
A new study out of the University of Pittsburgh found that men NEED alcohol to have a good time hanging out . . . but women don't.
The main reason? Men are too embarrassed to show emotions . . . even happiness. But after they've been drinking, they smile more, they're less inhibited . . . and they have a better time and feel closer to their friends.
Women don't need alcohol to show emotions, so they can have fun and bond without it.
