I'm pretty sure it's "Bite your lips" instead of "By your lips", and "Sleep arm-in-arm" is right. :)
I also think it's a great song, could possibly be about the break up but more likely is just about a girl or some sort of theme they're going for in the entire album. It's kind funny how the first song they released was "Up All Night" and this one's "After Midnight", they keep talking about night and nights they've had.
