pointless jargon

I went to a lecture tonight, and it was so jargon- and theory-filled that I didn't understand much of it. Thankfully, I liked the speaker's voice, and I thought some of what he said was interesting. He was wearing a lined jacket which reminded me of a magician, and I found that distracting. Also - and I wish I were making this up - he used the word "intentionality", which just boggled the mind. In context, "intent" would have worked just as well, and saved four syllables! It's even worse, to my mind, than "functionality", which is also awful.
