What is the definition of Pepsi1?

Pepsi1 is like the secret ingredient in every Pepsi fart you've ever heard, but don't worry, it's not the kind of fart that makes your nose wiggle or your stomach churn. It's more like the underappreciated, but still deadly, side effect of indulging in cola. Imagine this: "After a long day of debating the merits of cola vs. coca-cola, I decided to unleash my Pepsi1 on the town. It was a silent, yet potent, biological weapon that somehow still managed to cause chaos without anyone noticing."

Now, here's a bit edgier for you: "The CEO's Pepsi1 was so potent, it convinced the board to throw in the towel on their lucrative coffee merger deal, citing health concerns about the 'ecret weapon' inside their morning beverage."

"Pepsi123" is the internet slang for "Pepsi's digital selfie," aka, a person who posts endless, pixelated selfies of themselves holding a Pepsi can, usually with a caption that reads, "Just when I thought I'd run out of good vibes, I found my Pepsi buddy."

Now, here's a sentence that might send shivers down your spine: "With Pepsi123, I decided to prove my caffeine addiction was real, posting a series of selfies at 7 AM with the caption: 'I just woke up, my coffee's gone, and my Pepsi is a total mustache-twirling, 24-hour obsession.'"
