Couple lines in the song

Hello everybody! I heard a song by A Change of Pace and there were couple lines i didn't understand. It was:

"I met a girl once at a party
By 2 AM she's throwing up out back
She spends her weekends out in 10 feet"

and

"She thinks the third up line is boring"

I understand the very first line but i dont the rest.

Thanks for any helping.

By two o'clock in the morning, she was in the back yard vomiting (from the effects of too much drink, probably).

Thank you very much! And don't you know the meaning of the rest lines?
It would be just perfect ;) But thanks anyway!
