The average dude spends more than 40 hours a week at work, with maybe another 10 spent working at home. There's sleeping, which can take up to another 40 hours, and then we have to consider all the chores and family-oriented activities.

Guys need to unwind, to find themselves in the company of other Y chromosomes, to be themselves and not worry about the consequences. Political correctness has all but destroyed the male identity, and it has become impossible to act out our basic needs in public. Only when we're amongst our peers can we truly be ourselves.
Boys' night out can take many shapes and forms, depending on whether you're single, married or have entered the realm of fatherhood.
