Cheap wine and it's really cold.

The story:

Well I was in the back of my mum's car and I put my mixed CD on and this song came on and then I started singing along loudly and she looked at me and was like 'What are you singing?' and I was like 'Cheap wine and it's really cold.' Like, it make sense! And she told me the real lyrics and laughed for hours and even sang it herself. Still to this day, every time the song comes on she asks me what I think the lyrics are just to embarass me some more.
