stringularity 

The idea that the singularity representing an infinite mass is actually a "ringularity" connected to itself via cosmic strings. These manifest in the universe as distinct black holes, despite that an infinite mass cannot be contained to a single location in space or time by definition.

I once said the word "stringularity" to Brian Greene and he had a conniption.

Strangulationship

A state of emotional connectedness between two people, where one or both of the individuals are overwhelmingly possessive.

You know your in a strangulationship when your girlfriend is overbearing. My girlfriend never allowed me to be alone with her sister, initially having no attraction to her sibling I naturally thought this behavior was ridiculous. However, after years of overwhelming mistrust her sister and I would occasionally flirt to poke fun at her ridiculousness. This ultimately resulted in wild unadulterated sex, with her sister, in the upstairs restroom at a family gathering.
