Fuck ket, straight up. Heaps of K-Heads always down at the Dubstep gigs and they just disgrace themselves... falling over themselves, slamming in to you spilling your pint and dribbling all over their white crusty polo tshirts... not a good look. Never done it myself and from what I've heard/read doesn't appeal to me in the slightest so doubt I ever will.. the K-Hole can be a fucking hideous place.
