Small towns aren't exactly the most exciting places to live. They're giving a big "fuck you" to all of them because as teenagers, I bet they felt a lot of frustration being stuck in a mundane city. They want to "get out tonight" and do something fun, assuming from the whole tone of the song.
I don't think there's any deeper meaning. To me, it's a literal song.
