Itchy Butthole Day 

Likening the events or impending doom of a day to that of having an itchy butthole which is the uneasy feeling or "itchy feeling" a person may experience during post-defecation that occurs around the posterior aperture of the alimentary canal also known as your butthole. An itchy butthole day occurs when post awakening, things start going terribly wrong and make you feel like you have an actual flaming asshole, but in actuality, the world is just fucking you in the ass causing a similar, searing sensation in your soul.

I got up late and the kids missed the bus, I spilled my coffee when I got out of my car at work and once I got there I got verbally donkey punched by my boss and I could just tell it was going to be an Itchy Butthole Day.

The Second Day After Never 

Beyond never. It will not only never happen, but I would bet against it happening until all time ends, plus two days. (and what is a "day" after time stops?)

Q: Do you think the pope will become a muslim or a jew?

A: Sure, He'll become a Jew or a Muslim the second day after never.

fine structure day 

Like Pi day, but using the fine structure constant 1/137 = 0.00729. So, the day is July 29th.

You: "Happy fine structure day"
Random Guy: "What the hell is that?!"

early green day

The 'golden years' of the band's existance, many look back on this time with warm, fuzzy, and blurry memories. Early Green Day is most commonly cited to have existed from 1987-2000 and is known for such hits as "Going To Pasalacqua", "Paper Lanterns", "2000 Light Years Away", "Who Wrote Holden Caulfield?", "Longview", "Basket Case", "She", "When I Come Around", "Walking Contradiction", "Brain Stew", "Hitchin' A Ride", "Redundant", "Good Riddance (Time of Your Life)", "Warning", and "Minority" to name a few. Pretty much anything before American Idiot. Many 'h4rdcore 1337' fans tend to reference this version of the band to make pre-teen "21 Guns" fans feel stupid, which they should...

international beat-off day 

a very offensive and derogatory term for Labor Day (in North America and Thanksgiving Day (in Canada only).

international beat-off day is an offensive term because on these days otherwise productive male members of the North American workforce simply sit at home doing diddly-squat and beat off to porn. Too bad Thanksgiving is not celebrated in Canada during the month of Brovember.
