PSM (professor soul mate) 

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 »

PSMS 

When a woman sends an angry, scathing text message to your phone; mostly because it happens to be that time of the month.
