This is a common call and response technique used by MC's worldwide. The response is always "yes you can!", though a few inconsiderates may bite and say that the MC cannot, in fact, kick it. These people are assholes.
Biz: Can I kick it?
Dj Kool: Yes you can!
Biz: You know what I can do with the mic in my hand.
Q-Tip: Can I kick it? (Yes you can!)
Well I'm gone (go on then!)
