Text Insemination 

Text insemination is the art of "inseminating" the phones of everyone in your cell phone contacts list with a generic text such as "Hey, what's up" or "How's it going?" for the purpose of simultaneously having as many texting conversations as possible with as many different people as possible.

Jesse wanted to communicate with all of his friends at once, so he decided to initiate text insemination.

John and Jessie couldn't concieve, so john tried the radical new method called artifistal insemination.... There was blood
