A white kid who looks like he is in a gang, but isnt. Usually wearing a South Pole hoodie,a huge white tee shirt that looks like a dress, or a wife beater, and his pants around his ankles, and is usually smoking and threatening to beat you up.
A high concentration of them can be seen at the skatepark in Baraboo, WI, hence the name Baraboo Gangster.
May be seen in groups as large as 7, usually with a girl wearing not too much, and looks like her face got worked over with a shovel, she will probably be smoking too.
See that white guy over there smoking in his south pole uniform? He is probably a Baraboo gangster.
