Amigo de Qué?

Don't keep saying that a friend of yours
and your own wife tarnished your home
Confess coward, that was the debt
that sooner or later had to be paid

She was my girlfriend, whom I loved so much
one naive afternoon I introduced her to you
you felt envy, seeing her so beautiful
how did a poor man like me win her over?

From that moment on, behind my back cowardly
since you had money, you offered her more
until you convinced her, because you were rich
and one day my girlfriend left me for you

After a while, you made her your wife
with my own girlfriend you became my rival
and I remained poor, without money or girlfriend
while you with open arms, went to the altar
don't forget that one day, you invited me
to see her in your own home
just to humiliate me and then I saw clearly
planning the revenge that had to be paid

Seeing your wife, who was my girlfriend
I read in her eyes that she wasn't happy
your gold, your wealth wasn't enough
and that she desired me, I understood it

I returned at night, when you weren't there
and indeed my plan didn't fail
I took my revenge, and you caught me by surprise
you see, your gold was of no use

Now you can continue to proclaim
that I was the friend who betrayed you
look for her if you want, the debt
between friends has been settled

You are not my friend
Friend of what?
