The guy who got mistaken for Odell Beckham in a Tennessee airport last week says he loves to mess with people who mistake him for the real OBJ -- but there's one line he won't cross ... the vagina.
Meet Jamal Carter ... aka NOdell Beckham, aka FauxBJ ... who tells TMZ Sports he gets mixed up for the NYG wide out ALL THE TIME (especially by drunk people).
In real life, Carter is a recent college grad and current HS hoops coach from Tennessee -- but people mistake him for Beckham so often, he leans into it sometimes.
