Cover art for Firefly lyrics by Saves the Day

I agree with Bassistboy04 that this song may not be about drunken love but perhaps he walked a girl home and they finally confessed their feelings to each other. They're "drunk" on their love for each other which just totally fills them up and consumes them. This new found knowledge gives them energy, keeps them up and makes them go running wild and crazy in the streets at night because they are so happy. And making love, is so powerful and beautiful that it's like lightning. Damn, that light bulb metaphore is the most beautiful thing I've ever heard!
