During a policy discussion awhile back about New York issues, when Mr. Clinton began to pontificate, she told him that he did not exactly know what he was talking about and to hush up.
If someone pontificates about something, they state their opinions as if they are the only correct ones and nobody could possibly argue against them. Politicians like to pontificate about falling standards
To act like a pontiff; to be pompous, or express ones position as if it is absolutely correct
The pontificate of a pope is the period of time during which he is pope. Pope Formosus died after a pontificate of four and a half years. to give your opinion about something in a way that shows you think you are always right pontificate about/on. the position or period of being Pope
