This is the code name for PMS one of my Irish teachers used to use. It is what he believes is an accurate description of what PMS is.
Teacher #1: ''Why did Becca leave the classroom so suddenly? Is something the matter?''
Teacher #2: *With a very heavy Irish accent* ''Oh ya know, Psycho Princess Mental Tension situation.''
Teacher #1: *With a very British accent* ''Bloody hell. Sounds like it's going to be a massacre.''
