I think its about a guy who has a fling with a girl that's already taken...by someone much bigger than he is apparently! He's saying he doesn't want any trouble, and 'too much sugar for my sweet tooth' maybe means even though she's hard to resist she's more trouble than its worth? Not sure about the last bit fits in with my intepretation though :S Anyway love the song!
