Headbanger

A fan or preformer of EDM music of all sorts, such as Dubstep, Drumstep, Drum and Bass, Hardstyle and so on. Normally, the motion of rocking your skull back and forth is to mimic the beat of the song, otherwise if you do so out of context, you'll look like you lost your bloody mind.

"Good god, look at that fucking headbanger go!" Jim said. "Well, what else do you do when you listen to Excision?" Isaiah said.
