Floyd Mayweather Sips from Solid Gold Chalice While Drippin' In Diamonds

Here's another gross display of wealth by Floyd Mayweather -- who's poor-shaming his followers by drinking out of a gold chalice while wearing a TON of diamond necklaces and bracelets.

Oh, he's also standing in a pile of money while wearing a Versace robe.

"Real Royalty," Floyd said ... "Everything I got on is real, even the cup I’m sipping out of is real gold and if you don’t like it... you’re a REAL HATER!"

"Now that’s some real sh*t."

Mayweather REALLY wants you to see how rich he is ... he posts stuff like this all the time, but it's still crazy.

Dude has reportedly made close to $1 BILLION from his pro fighting career.
