Brownshirt 

Slang for a Nazi or fascist pig. Derived from the brown shirts worn by the Sturm Abteiling (SA). Brown was the color of the Nazi party in the 20's and 30's, much as red and blue are respectively associated with the Republican and Democratic parties in the US now.

Side note - the Schutzstaffel (SS) primarily wore black uniforms.

Nazi: "I love Hitler. Mexicans suck."
Punk: "Fuckin' brownshirts. Let's bust some heads."
Mexican: "Hell yeah."
