There was the following sentence in the article titled “Pope Francis tells Pope Benedict to stop rolling his eyes in meetings” in May 2nd New Yorker magazine - http://www.newyorker.com/online/blogs/borowitzreport/2013/05/pope-francis-tells-pope-benedict-to-stop-rolling-his-eyes-in-meetings.html
Pope Emeritus Benedict’s return to the Vatican began on a sour note today as the current Pope, Francis, reprimanded him for rolling his eyes sarcastically during meetings, observers said.
The trouble started when the former Pope showed up at a meeting that “Benedict wasn’t even invited to,” a Vatican source said. After about ten minutes of suffering through Benedict’s sighing and eye-rolling, Francis “totally called him out on it,” the source said, adding, “What Benedict was doing was totally disrespectful. Plus, he is supposed to be retired, so he shouldn’t have been wearing his Pope costume.”
Though Oxford English Dictionary defines “call someone out” as
- summon someone to deal with an emergency or to do repairs
order or advise workers to strike.
(archaic) challenge someone to a duel,
none of the above definitions seems to fit to “Francis ‘totally called him out on it.’”
There is no entry of the idiom, “call someone out” in either Cambridge or Merriam Webster English Dictionary.
It looks like the phrase, “Pope Francis “totally called him out on it” to mean he was totally upset with Benedict’s presence accompanied with exaggerated gestures during the meeting, but I’m not sure. What does this sentence and idiom,'call sb out on stg' mean?
