The state of having so much swag, that it is considered nasty. One can say that once the maximum level of swag has been reached, they can only simply be known as "That Guy." Also, if you claim to have swagg-nasty but you don't, then you like it anal.
Damn, that kid looks like he has swagg-nasty. He flicks his nose with such style!
