A short story about a catch phrase - a job post by Corey Farrow

About the job

I'm looking for a writer to write a script about the development of a catch phrase.

Here is an outline I would like the writer to use. Man plays baseball and hits ball into the sky and hits a spaceship that falls to Earth, killing the Alien inside of it. He has dinner with friends and he starts a catch phrase in honour of the alien. 

Next, people all across the world use the catch phrase. 

I would like the story to be narrated with explanations to how it began and the context of its use.
