If this "Song" is about Katy dating, and having a 2 year relationship with John Mayer after trailer trash was dumped by him. In my opinon John upgraded and this is from someone not even a fan of katy or her music. Bad Blood taylor? Really you wrote 3 or four trash songs about Mayer.
And only one apology. Wait it's what you to do to anyone stupid enough to date you. No version of the song would have great. Trailer is well Trailer trash in designer clothes and she never lived in a trailer park. S.
