I learned from Mahalanobis, we now have a new euphemism: "constrained discretion". It is taken from Ben Bernanke's statement, and it means "a state where you have no idea what you're doing" -- my rephrasing Mahalanobis.
Speaking of euphemism, here's another one: "My priors shifted". Meaning: "I changed my mind". (via Arnold Kling).
