nixie fighter
n.— «From a former tough, a so-called nixie fighter (an old police term for one who fights officers): “Brings back memories. Gawd, how I miss em! I was part of a crowd that proudly fought the cops outside a 7-11. I can still hear the obscene taunts the women screeched, the surreal lighting, the way it affected the color of a bottle if you threw it and the funny shadows it made on the potholes in the parking lot.”» —“‘Bloody Third’ spurs eloquent recollections from readers” by Bill McClellan St. Louis Post-Dispatch (Mo.)
