People are roasting each other at parties at work events around the fire. It's so fun. People are busting each other's chops and it's a sign of affection truly. It's a true test of love and friendship: can you make a man laugh at himself? So what makes a good burn? Go after targets you love and respect. And hit 'em hard.
