Cause baby now we got bad blood. What if bad blood is a song about a girl who dumped her boyfriend because he gave her AIDS.
Baby now we got bad blood - AIDS affects the blood, and it's "bad blood"
We used to be mad love - she really loved him
Now come and look what you've done - angry at him for giving her AIDS, yelling at him for giving her an STD.
Now we got problems - they both have AIDS.
We can't solve them - there is no cure for AIDS
Why did you do this I was thinking you could be trusted - he told her that he didn't have AIDS, but it was a lie and she is regretting.
Oh it's so sad to think about the good times - they know they are going to die.
You can figure out the rest. BOOM.
