zeromph 

When riding a bicycle while cleated onto the pedals the rider comes to a complete stop, fails to release his feet from the pedals, and crashes to the ground at zero miles per hour.

I got to the top of the hill, came to a stop, and zeromph! There I was laying in the crosswalk, still clipped in.

Zerophiliac 

Any person with Zerophilia, the rare genetic condition affecting those who possess an extra "Z" chromosome in addition to the standard gender-determining X and Y chromosomes. Following their first experience of sexual intercourse, Zerophiliacs may change gender whenever they are sexually aroused. The International Organization of Zerophiliacs provides testing services and resources for those with Zerophilia.

When she noticed her boyfriend, Jake's, penis occasionally disappeared, Mary submitted his hair for testing to The International Organization of Zerophiliacs and confirmed her hopes: Jake is a Zerophiliac.
