** WARNING: Horrible language, violent threats, and homophobia **
Adrien Broner just re-ignited his beef with Floyd Mayweather ... calling the Money Man a "bitch," and it's all over his relationship with a rising boxing superstar.
The boxing star is Gervonta "Tank" Davis ... an undefeated champion and member of Mayweather's Money Team who recently called out Broner, demanding a fight with him.
Broner apparently took the challenge as the ultimate sign of disrespect, claiming he and Davis are pals, and alleging Floyd tricked the kid into making the challenge, and he ain't happy.
