James Corden ribbed BTS fans, a.k.a. the "Army," with an "ageist" joke that failed to resonate with them on social media.
The Late Late Show host posted and later removed the clip of his comment in which he talked about the wildly popular South Korean boyband's visit to the United Nations General Assembly (UNGA) in New York on Monday.
Corden prefaced his joke by referring to the seven-member boy band as "unusual visitors" and theorized why they would be found at such a formal gathering, even though it was their third appearance at the U.N.
"People say why are BTS there? The world leaders have no choice but to take BTS seriously."
"At the end of the day, BTS has one of the largest armies on planet Earth."
What followed next was the statement that riled the BTS Army, which is comprised of fans of all ages and not exclusively teenagers.
"Historic moment. It actually marks the first time 15-year-old girls everywhere found themselves wishing they were Secretary General of the United Nations António Guterres."
What fans took to be an ageist remark rubbed many of them the wrong way, especially after Corden had invited BTS on multiple occasions on his show.
He was even dubbed "Papa Mochi" because of his tight rapport with bandmember Jimin, a.k.a. "Mochi."
Corden invoked a trope about boy bands throughout music history having a fanbase primarily consisting of teenage girls, but his attempt to roast fans with it did not land well.
Now, some members of the BTS Army are demanding an apology from the television personality.
Some people were more forgiving of the host but identified the root of the issue.
For their third appearance at the United Nations and to kick off the gathering on Monday, BTS screened a video performance of "Permission to Dance," which was shot on the grounds of the U.N. headquarters of New York.
The group also discussed climate change, digital community, vaccines, and the younger generation's role in shaping a better future.
More than one million viewers watched their appearance at UNGA, online.
