It looks like Russ really meant it when he said stop playing with him! Russ and crew caught Smokepurpp slippin' backstage in Germany and decided to beat the breaks off him! This all happened because Smokepurpp was talking recklessly on twitter to Russ, and took things further by posting a photo of Russ's little sister to his page!
The day after the fight, Russ caught Smokepurpp again back stage and asked if Purpp was "done talking?!" Based on his reaction, I think he is.
