This can be done one action at a time. Every time someone claimed expertise in something I know, I ask about it. If someone uses a buzzword I don’t know, I ask them to explain it in plain English. And I ask again if they define one buzzword with another. And if they namedrop a mutual friend, I ask the connection their opinion. BS is a cancer. Unless you’re drinking with friends, in which case it’s entertainment.
