Floyd Mayweather took his entire TMT entourage to the famous Hustler store in Hollywood early Wednesday morning ... and made a "Supermarket Sweep"-style run through the adult toys section.

Freaky Floyd hit up the fetish wall. He grabbed a leather whip and cracked it a little bit. He perused all the fun restraint devices ... and he did it all with a bevy of lovely ladies in tow.

Also, his bodyguards were there, too!

Maybe Floyd was doing some Xmas shopping -- but forget "nice" ... he's all about the naughty!
