I'm trying to work out which one it is. It could be both, it could be neither, but I think it's one.
Basically, it's the whole party atmosphere where people are being loud, getting hammered and are having "a good time". It's where people are dancing to cheesy music and shouting the lyrics drunkenly. It's where people are making pointless small-talk that will be eventually fruitless. I really do not enjoy it at all. It just makes me want to walk away instantly - it's so painfully embarassing and Ezra-repellent. I see the whole atmosphere, and it depresses me. I need to get away.
