Lyrics:

She left on Sunday
And he died on Monday
A girl who's killing a boy
And she left in her own way
And he died in the worst way
A girl who's killing a boy
A girl who's killing a boy

Take it or leave it
You'd better believe it
You know that it's real
And now you're starting to feel it
We had something good, yeah
and then you go and break it
and break it, and break it, and break it 'til it's gone
And he died on Monday
A girl who's killing a boy
A girl who's killing a boy
