Odell Beckham Jr. -- My 1-Handed Catch ... Is a DANCE MOVE

Odell Beckham Jr. reenacted his most famous catch ever Sunday night -- the 1-handed grab -- performing it as a dance move at a Miami nightclub ... only this time, he played the role of Eli Manning.

OBJ was at LIV for DJ Clue's birthday party -- joining huge stars like Floyd Mayweather and Jim Jones -- when he and a friend decided to bust out some football-inspired dance moves in front of the crowd.
