Boxer Has $250,000 in a Duffel Bag. He's Going to Use It for Something 'Vulgar' If He Wins.

They call it the "pregnant duffel" because it sits, crammed full of cash, in a corner of Floyd Mayweather Jr.'s Las Vegas MGM Grand changing room.

If he wins his huge Saturday fight against Manny Pacquiao, the bombastic boxer Mayweather has the money earmarked for one purpose, the Daily Mail reported: a massive strip club party.

The amount: $250,000, more money than most Americans have in their retirement accounts.

The Daily Mail labeled it "vulgar."

Of course, it's chump change compared to the $200 million Mayweather is expected to make for Saturday's fight.

An insider told the Daily Mail that Mayweather expects to win the fight, and the victory shindig will feature Justin Bieber and "wall-to-wall money and strippers."

On Twitter and Instagram, Mayweather consistently shows off his extravagant spending — funded by his $400 million fortune.

Mayweather has been undefeated in his professional career so far.
