Well, going off of this transcription, it sounds like he's making up his own fancy word, possibly poking fun that all the big words used in the historian's quote. It could be combination of a few different words, but I'm not exactly sure of which ones.
I'm guessing you copied your version from the closed captioning. If I understand correctly, that's often automated and does necessarily accurately reflect the speaker's words. Upon listening to the video, I believe he might be saying
In fact, I love some foul licentiousness.
