Whoa!
One of Cassper's fans called him to task about getting "too cocky" on Twitter.
This caused quite a stir on the social media platform, with more than 20 people retweeting the status.
"Judging from his tweets Cassper Nyovest is becoming so cocky," tweeted the fan.
Cassper replied by tweeting back: "I wish you could meet me and then judge me."
We reckon that's a fair response. What do you guys think?
