what would you make of this behavior?

in my first day of class at university, i'm in a night class with a male teacher. i walk in the room he's sitting at a student desk with his feet kicked up and scrolling on his phone, he kind of snickered when i walked in the room. i sit at the front, for most of the lecture he stands directly behind me talking over me. he said his brain is fried after teaching all day. then we do a group project, he paces the room smacking his glass juice bottle in his hand.

i'm still sitting in the front left corner of the room he paces around the class multiple times in a circle, every time he comes around his foot knocked against my table leg or backpack. when we did another group project, constructing a model he sits closely next to me while i'm working, scrolling through his phone.

when we do a group discussion of what we made he stands directly behind me the entire time while i'm discussing with my partner while he is scrolling through his phone. when we discuss among a larger group he sits near me again, breaks his wood toothpick/food skewer in half and places it on my desk. then makes a passive aggressive comment about my partners design which she designed based of what i said i liked...

what do you all think? have you encountered something like this before? does this sound like he's on drugs? what would this behavior be indicative of?

Sounds like an adjunct who really doesn’t want to be there. It’s a side gig, he works full time somewhere else or has multiple adjunct gigs at different schools. And he also sounds pretty awkward and unprofessional.
