This song is explaining what the typical boy would do these days. They say that they love you and then cheat, leave you home alone, and have fun without you. She is saying that she wishes that she could be the boy and drink beer chase girls make their owns rules and still have the girl they supposedly love. She is now telling them that you can't treat women any kind of way and if you love them then you should treat them fairly. No one wants to be treated that way!
