When a mommy and a daddy love each other very much, and they both have recessive genes, they give birth to something fouler than the meanest monster: an OP, or an original poster, namely of the website MyLifeIsAverage. The OP thanks to the fabled, horrifying "OP gene" steadily becomes a stranger and stranger individual as time goes on, beginning mainly at the age of two. People who hold this gene often tend to gain freakish obsessions with ninjas, unicorns, and fortune cookies. They are physically, often, unable to comprehend correct grammatical knowledge. There is no cure for OPism as of yet, though doctors advise what is playfully referred to as a "vasectomy" as a preventative action.
OP: "Today, I was hanging out on my college campus when I happened across a dinosaur. I rode Ralphie, my new pet dinosaur, into town, where we saw a guy in a banana suit sprinting away from a a guy in a gorilla costume. My professor then shouted "THAT'S WHAT SHE SAID" and received the Best. Highfives. EVER. Ralphie and I rode back outside, making sure not to pass a single crunchy leaf, when happened upon my little brother and my grandfather having a massive pirates versus ninja fight with Nerf weaponry. Best family ever? I think so. Then the Rolling Stone's song "Sad Sad Sad" came on my iPod. It was very ironic. Then we went to Wal-Mart and laughed at Twilight fans. Then, who did we see next you ask? Why only HARRY POTTER! We sang "Goin' Back To Hogwarts" with him 5 million times, and bid him adieu. On our way out of Wal-Mart, we saw Google destroy Yahoo yet again. IT. WAS AWESOME!!!111!5one"
