～を煙に巻く boggle someone's mind
(Kenichi comes out of the bedroom)
Rachel: How was your English discussion class?
Kenichi: I'm so glad we're not doing it in person and I have the option of disabling my video and audio. I sometimes need to disappear from the screen and take a deep breath.
Rachel: I thought you liked your class.
Kenichi: I usually do, but I think the guy whose turn it was to choose the topic of discussion today just wants to boggle people's minds with the topics he suggests. You know, to show off that he's knowledgeable about obscure subjects.
Rachel: Was everyone else as bewildered as you were?
Kenichi: I don't know, but I'm pretty sure they weren't enjoying the session very much.
Rachel: What was it about?
Kenichi: A Marxist interpretation of the Japanese Constitution. After 90 minutes of so-called discussion, I still had no idea what he was on about!
Rachel: Did the guy who came up with the topic have a lot to say about it?
Kenichi: He's the only person who had anything to say about it.
Rachel: I'm sorry to hear that. Whose turn is it to choose the topic of discussion for your next session?
Kenichi: Me. And I'm going to make it as enjoyable as possible for everyone.
