I Piss on Marchisians. When you don't feel comfortable with marchisians and you don't want to stay with them.
"NO, I WOULD NOT LIKE TO STAY WITH THEM RIGHT NOW"
"Would you like to come with me to the beach with the marchisians" "PSM"

A professor you feel an emotional and intellectual but completely platonic connection to. It’s THAT professor that will talk about all the subjects that you’ve always wanted to talk about, the one that can keep you interested for hours about that one topic. It’s the professor you’ve always dreamt to have a conversation with.
« okay I’ve met my PSM (professor soul mate) today. He is the professor I’ve always been waiting for »
