Speaking in the native tongue of a swagger guy; to use one's tone of voice and choice of vocabulary.
Guy#1: "Hey dude, what the hell is that guy at the bar in the sick threads talking about? And why are those girls so attracted to him all of a sudden?"
Guy#2: "Oh that guy? He's Swaggarian. Only women and other Swaggers know what he's saying. Women usually find the native tongue of a Swaggarian gentleman attractive."
