Here's another one that pissed me off, not so much a phrase, as something people say.
When you meet somebody new and ask them, "What sort of music you in to then?", I hate people who say, "Oh, everything really." No. You're not into everything at all. I like Thrash Metal. Tell me, do you like Reign in Blood by Slayer? No? Didn't think so. How about Mayhem? No? Ok then, what about Pavane by Faure? So you don't like 'everything', you just haven't got enough confidence in yourself to say what you like, or you are unable to convey what it is you like because of your limited intelligence. OR more likely than not, you are in fact just a boring fucker who I now want nothing more to do with.
The other one in a similar vain is when people when asked what they enjoy doing, say, "Meeting my friends and having a laugh."
Really? Honestly? You like having a laugh with your friends? Fucking hell, you outgoing individual, you! God, that's mental. I don't know anyone else who likes having fun with their mates, you're so unique. I'd much prefer to meet up with nobody and cry and generally have a shit time, but you, well, they broke the mould didn't they!
