Swag Nasty means you are swagged out and when you enter the room everyone can sense the Swag Nastiness. If you are Swag Nasty you like to break things and shit on people's feelings. You walk around like you are the shit, because you are the shit. And you are the shit because you're Swag Nasty

Swag Nasty means you are swagged out and when you enter the room everyone can sense the Swag Nastiness. If you are Swag Nasty you like to break things, eat cereal and fuck shit up. Swag nastys are usually tall and attractive, in some cases they are short but that is rare. Swag nastys are swagged out swaggers who are swagged to the max. You probably notice that people always want to be your friend, that's because you are fucking swag nasty. You walk around like you are the shit, because you are the shit. And you are the shit because you're Swag Nasty.
Look at that guy over there he is so hot, he's got bitches and cereal. he's so swag nasty.
