If you're being genuine: just say you like Refused and The International Noise Conspiracy and leave it at that.
If you're being sarcastic: theres no need to take the piss you cocky little prick. There loads of bands that are 'in' on the metal scene that people always go on about in here and I haven't a fucking clue who they are, so just......just....nob-off ok. If you carry on with this 'in' kiddie punk (even though i dont listen to punk) crap, you'll be forever labelled as a shithead in my books and then there'll be no chance of a shag, so leave it out
