Manhattan Project

When having anal sex with a girl you cum inside her, withdrawl, then slap her ass/push on her midsection in the front to induce her to fart your cum out. Works best with doggy style or during snowmobile.

Dude, Jovann Manhattan Projected on me last night and it ended up on my own cum ended up on my chest.

Manhattan Transfer

Sex act in which a fart is transferred from one partner's anus to the other partner's anus through a straw.

Travis wanted to try a Manhattan Transfer but we didn't have a straw so he just farted on my balls.

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."
