I'm not looking for a translation of lyrics, just what "Полавинка" means and the English translations of this persons name: "Кристина". Supposedly it's one of my friends favorite songs and I am trying to figure it out....might help in the future. If it's not too much, if anyone knows a place on where to get the lyrics (even if they're in Russian), that would help out a lot. I'll try and get them translated somewhere since wouldn't be the best place to post them *short phrases*

Thank you guys all again.

It all depends on the context but "Пол
овинка" literally means "half", or like in your previous question, it means "partner in life" or "better half."
Now, "Кристина" = "Kristina" or "Christina."
