Christofer Drew has admitted that he did not write this song, nor is he the one singing it. He has also said he does not support it's message.
The person who did write the song, used a computer program to change their voice so that it sounded like Chris's.
This song is basically about two teenagers who have s**, but know that their parents would forbid them doing so, but they think they really love each other, so they decide to start to drink and continue to have s**.
Look at Chris' other songs. This is so unlike them, it's pretty obvious, even without what my first paragraphs above, that this song is not his. I mean, he pretty much tried to deter teenage s** with his song "Losing It".
