Mandatory fail party 

The term used for a mandatory tutoring session or something of the like that you must attend when you fail a test. Instead of saying mandatory tutoring, you say mandatory fail party to make it not sound as lame.

"Shit! I failed my psych exam. Now the professor is going to make me go to mandatory fail party."
