Premature Auto Flushing 

The flushing of an automatic toilet bowl prior to taking a shit.

This is known to happen in corporate offices with automatic flushers and after a great deal of effort has been expended to carefully lay down the paper on the seat...right before you sit down, the toilet flushes taking all the paper with it...forcing you to start again...

Andrew had to take a massive crap and took great care in applying the paper to cover all parts of the dirty seat...as he turned to drop to his knees, a premature auto flushing kicked in...requiring him to hold back with all his might as he re-applied paper....

Premature Ventricular Contraction 

when your heart skips a beat.

may be perceived as a "skipped beat" or felt as palpitations in the chest. In a normal heartbeat, the ventricles contract after the atria have helped to fill them by contracting; in this way the ventricles can pump a maximized amount of blood both to the lungs and to the rest of the body . In a PVC, the ventricles contract first, which means that circulation is inefficient. However, single beat PVC arrhythmias do not usually pose a danger and can be asymptomatic in healthy individuals.1

Babe, you make me have premature ventricular contractions. <3

preNatal 

A time before Microsoft's Project Natal was revealed. Referred to as a simpler time by many as we didnt have to get off the damn couch to play a game.

Guy 1: Dude! look at this old game controller!

Guy 2: Woah! It has buttons and you have to hold it!

Guy 1: Yup, this right here is some ancient preNatal technology.

Guy 2: Gotta love the good ol' days.
