Don't respond, just give an uncomfortably stare. If they don't walk away, ask "why are you still here?"
If you have to talk to them, only answer a question or comment with a question, never a real answer. Also don't actually address his dumbass comment, just switch it to questions about why anyone would even care what he thinks.
Why are you even talking to me? Why would anyone care what you think? How is it you think anyone cares about your opinion?
Not everyone can be as smart as you Eric.

Can't help it mate, gotta live with it.

Sorry bud, seems like I spent too much time with u.
Or
You can do better, keep trying.
That's usually how I respond, not really into getting personal. Just keep it simple.
Ask them a simple Maths question that needs a bit of thought, give him a few seconds then say "thats what I thought, who's the dumbass now?"
From then on call him a dumbass before he gets the chance to.
Troll him back some how!!
"The fact you're judging me like that while you don't even know me, says more about you than it does about me."
And then you need to say it in the same way Chuck Bass would say it.
Call them one back and laugh
