Someone who only likes bands so long as it says they're allowed to in kerrang magazine/any other music publication.
If they are to hear a band or song who have not been mentioned at all in Kerrang then they usually say that they're 'ok' just to play on the safe side.
Person 1: Hey, what do you think of this band?

Kerrangfag: *Thinks: hmmmm, they're not bad... but Kerrang haven't mentioned them yet...* Yeah they're ok...

-Week later after Kerrang write bad review on said band-

Kerrangfag: That band you showed me are shit!
