not to say

As well as; in addition to being. Used to indicate a stronger, more emphatic, or more candid description to what has just been written or spoken of. I think it would be an incredibly ill-advised, not to say downright foolish, not to accept his offer at this point in time. His behavior is boorish, not to say contemptible.
