A veritable avalanche of chinchillas, as happens from time to time in the South American Andes. Chinchillas are known for their prolific mating habits, and over time, a dangerous chinchilla buildup can occur in elevated regions. Warming conditions lead to instability, and evenminor sounds or vibrations can trigger a catastrophic chinchillanche.
Mark: "Did you hear about Edmund getting killed?"
John: "Oh my God, no! What happened?"
Mark: "He was hiking in South America, and got buried in a motherfucking chinchillanche!"
Chinchilli Day celebrates the victory of the tiny pueblo town of Topiticca over the uprising of their pet chinchillas. Although many attempts were made to negotiate a ceasefire, the fighting continued over three long days until the last of the chinchillas was gone. To this day the town’s victory is celebrated by the descendants of Topiticca and all chinchilla haters.
Note: Because little is known of the actual dates of the conflict, there are those who believe the town of Topiticca never existed and Chinchilli Day is actually an elaborate excuse to spend an extra day partying in Las Vegas.
I can't come to work Monday because I will be in Vegas celebrating Chinchilli Day
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
