the above link can help you ...
if you need a verb, consider it as a contraction of 都係 or 都算係, "already be" or "already be considered"

睬你都傻啦 would then be
I'd be stupid for talking/replying to you
I'd be considered stupid for talking/reply to you
essentially meaning, they're not going entertain what you have to say.

in english it would be similar to
"wouldn't give you the time of day"


睬你都傻 by itself means
"i'm not going to dignify that with a response"

you are being silly

nonsense

I am not going to comment on that

forget it

I would stupid for talking/replying to you
I would be considered stupid for talking/reply to you
essentially meaning, they're not going entertain what you have to say.

Notices you to be all silly
