I have this feeling that I've seen and then forgotten a word which specifically describes a professor / lecturer who teaches in multiple universities. (Not just a visiting professor)
"I hear Mallory is a ___________ now. It certainly fits his character, but I do worry for his cardiovascular health."
I think that this sense of the word might be a secondary definition to the word's main usage. Does such a word exist? I can't find it anywhere in my search history or online...
But I can't shake the feeling that I definitely saw it somewhere on google definitions while defining another word!
