Swag is for boys. Class is for men.
Swag is the face you wear for the rest of the world. It's a defense mechanism - self preservation. It works well in bars, when you want to create that enviable aura around you. But when people start to know you, it'll wear off. In fact, coming close requires you to take off your swag. Your swagger doesn't doesn't mean you don't give a fuck. In fact, the bigger the swag, the more you care about what people think of you.
