ICYMI -- Sterling's groomsmen made quite the entrance at the wedding reception earlier this month ... shoot-dancing their way to the stage while Kid's "New Freezer" played over the speakers.
"They was killin' that sh*t, bro. That sh*t was fire," the New York native tells TMZ Sports.
Of course, OBJ is no stranger to dancing his ass off -- he sent a message to his haters via his sick moves earlier this week ... bustin' out a routine to Flipp Dinero's "Leave Me Alone."
BTW -- we're not too sure, but it seems like Rich the Kid might want you to buy his album.
