The problem is when you're thinking about what to say you're buying them time.
Verbal distraction may be very useful in MUC but if it's gone beyond that to a real fight then to quote Tuco " when you're going to shoot, shoot don't talk"
Trying to be clever verbally is going to slow your response down dramatically. And unless you've done this plenty I fear you may not be capable at all. I know I'm not. My last one started with me shouting JESUS FUCK! as I drew. Not in an attempt to distract anyone but rather in the manner you swear when you stub your toe.
If you haven't done ECQC then go book for one right now.
You you seem to be trying to build a defensive response in a drill to an imaginary fight. I wouldn't want to be building a reflexive response that intricate to such a specific set up. Build skills of course but that's a pretty specific dance you've got going there.
