Lyric discussion by superstarwannabe 

(On the previous posts) I agree, this song is kinda straight to the point. The chorus simply screams, "do whatever you want, just be true to yourself!"

But the part "what the fuck do you know" has an angry feel to it - it's like the parents are trying to give her advice, they think they're wiser than her and that she doesn't know a lot of stuff in life coz she's still young. It's an angry way of saying "what? you don't need to tell me what I should do! I already know what you're talking about!"

An error occured.
