You Keep Your Lips And What's Behind Them Zipped

You keep your lips and what's behind them zipped. No explanation do you give for this. But then you expect understanding given for it. And you're bottled up. You're bottled up! You do a tantrum dance and go into your fits. You spit words of venom with a delivered hiss. And then you wish somebody to bring to you gifts. And you're bottled up. You're bottled up! What makes you think you are deserving of it? You're not even using those you've been blessed with. You curse the Earth and spit on it, When you should give it a kiss! And you're bottled up. You're bottled up! And you're bottled up... With a half filled cup. You keep your lips and what's behind them zipped. No explanation do you give for this. With your jaws tight together like a big hypocrite. And you're bottled up. You're bottled up! And you're bottled up... With a half filled cup. You're bottled up! You are bottled up. With guts sucked in and ready to explode, On a moment's noticed!
