[bad word]  dead

It was late last summer
I found out you went to one of those places
That men go to meet, to sow their seed, spread disease
Could swear you swore that you were mine

What the [bad word] was I thinking?
My heart's been sinking
Down through my stomach, right down to my feet
What the [bad word] was I thinking?
My heart's still sinking
Down to the stomach, down to my feet

Could have sworn that you were mine
Could have sworn

I tell [bad word]  [bad word] 
I tell the [bad word]  [bad word] 
I tell you the [bad word]  [bad word] 
I tell you the [bad word]  the [bad word] 

What the [bad word] was I thinking?
