hug it out, bitch

venturing out of an SF stripclub the other day , we were shocked to see some metallica band member/douche at the venue. after the usual 'napster' pleasantries were thrown he approached me in some confusing way, to which i says 'you wanna hug it out? let's hug it out' ... and he says to me 'im not touching you dude.' which i though was wierd cause i always thought metallica was a gay metal band. so then he takes a picture with a female member of our party and we head out . im not sure what any of this means.
