Person who is obsessed with all forms of the electronic genre of music. Finds it as a way of life and a way to relax. Beat heads are usually those goofy kids you see at electro house shows with glasses and a smashed bottle of water, asking someone for a cigarette.
"I've seen that guy at every house night in this club for the past 4 months, what a beat head!"
"Dude, i think i have serious problem, i've become an obsessed beat head"
