In the video, Emma Stone plays a BTS fan and has a sleepover with SNL cast members. The entire stage is plastered with BTS posters.
Some people thought it was realistic, as committed fans are already camping outside the set in the hope of catching a glimpse of BTS, who are this week's musical guest.
Some fans related to parts of the clip.
But a lot of people are concerned about what they say is a belittling of fangirls in the promo video.
And they say that women's interests have been infantilised.
Many are bringing up this past video of Yoongi saying that fans are often belittled.
In the video, Emma Stone says "no boys allowed" — a line that has struck a chord with many fans who say the fandom is far more diverse.
But people see the other side of the argument too.
However, some people have seen the comedy in the skit.
You can watch Emma Stone host Saturday Night Live with musical guest BTS this Saturday.
