Haha. Yeah, I still use, “hang up.” I’m going to try to catch myself using that one too. Thanks for the heads up. If O’Keefe knows better, why does he still use these terms? Do you think he is stubborn or just goofing around?
I would describe O’Keefe’s usage as “colloquial” or “idiomatic”. Some words and terms graduate to a broader sphere beyond their origins. For instance, we all use the word “phony”, even though its origins is in the distortion of the voice one heard on early telephone lines. Now it is a synonym for “fake” or “counterfeit”.
O’Keefe may also use the term “film” to his marks as a way to imply permanence to the recording, as opposed to the wordier and more transient sounding “digitally streamed or recorded”.
