Floyd Mayweather's Dad -- Taunts Pacquiao With Victory Poem

Floyd Mayweather's father is FIRING MORE SHOTS at Manny Pacquiao's camp ... calling him a loser with a pathetic trainer ... and he's doing it all through the majesty of poetry.

Turns out, Floyd Sr. has been dabbling in the rhyming arts for a while -- and has even been putting together a book of his best work.

And after Saturday's mega-fight, Papa Mayweather felt the inspiration to tap into his inner Robert Frost ... to deliver the most poetic smacktalk we've ever seen. Enjoy ...

The fight has taken place..
Manny's title? Lost without a trace.

As Me and Floyd
Entered cheerful embrace...

I glanced to see the look of disgrace on Freddie's Face.
I have changed My pace

I can now look them in the face
And say:

I must confess You tried Your best.....
And As We saw there was no contest.

FLOYD is simply the best!

Now just like I said
Freddie the Roach is Dead!
