Examples:

"Fact is, you can find good pizza from Memphis to Salt Lake City. But you have to look a lot harder than you do in Orlando. So, stop with this nonsense already. Similarly, let's abandon the absolutes. This place is THE BEST. That place is THE WORST. These things are entirely subjective and ranted about on the internet by a small but exhaustingly vocal contingent of zealots, many of whom I suspect enjoy pontificating far more than they enjoy pizza." — Amy Drew Thompson, The Orlando (Florida) Sentinel, 8 June 2023

Did you know?

We hate to drone on, so we’ll give you the TL;DR on pontificate. In ancient Rome, a pontifex (plural pontifices) was a member of an important council of priests. With the rise of Catholicism, the title pontifex was transferred to the Pope and to Catholic bishops. From pontifex, by way of Medieval Latin, comes the English verb pontificate, which in the early 1800s meant “to officiate as a pontiff”—that is, as a bishop or Pope. (Note that the noun pontificate), which refers to the state, office, or term of office of a pontiff had been borrowed directly from Latin in the 15th century.) By the late 1800s, pontificate was also being used derisively for lay individuals who spoke as if they had the authority of a member of the clergy. To this day the word connotes an air of spurious superiority—one might consider this sense of pontificate to be the spiritual forerunner of mansplain.
