Adrien Broner -- I'll Take My $50k In Hundreds ... Rips Up $20s

Adrien Broner only likes his cash in $100 BILLS -- 'cause when he found a bunch of twenties in his $50,000 stack ... he ripped 'em up.

Broner pulled out the cash for a crazy photo shoot -- at one point throwing the money on the floor to brag that he was stepping on Franklins.

Next thing you know ... he's tearing up the Jacksons.

As for the rest of the cash -- don't worry, Broner put it to good use ... making it thunderstorm like a boss at an Ohio stripclub.
