DAY-X 

The day after any drug test in which the testee/s will ingest copious amounts of illicit substances.

Dude, DAY-X ripped me a new anal cavity.

x-day 

X-Day (the SubGenius rapture), voted Time Magazine's 'Scam of the Century', was supposed to have swept the SubGenii from the earth on July 5th, 1998. This was a faith-shattering event for many x-ists, who were not loaded into the pleasure-ships filled with sex-goddesses. Though it hasn't stopped the SubGenii from gathering every subsequent 5th of July devivals, in hopes that they may have been off by a few years.

I hope that there's a lot of bug-porn on those pleasure ships, come x-day.

A two volume Japanese comic book about four people and their plot to blow up a highschool. See manga.

Did you think the second volume of x-day was a letdown?

X-Boxing Day 

It is the one day over the Christmas holidays where you are entitled to uninterrupted X-Box entertainment without the apprehension of having to switch it off.

This remarkable day occurs either on Boxing Day or on some other agreed day with your spouse.

Whilst it is lovely spending time with family, this is an effective pragmatic settlement that helps to soften the unpleasant experience of unwillingly enduring dreary Christmas TV, imposed through common family demand.

"I hear you are not spending Christmas at home this year, is there any chance you could jump online for some Special Ops?"

"No, but I do have an X-Boxing day agreement. Unfortunately I am ill-fated to be in an unfamiliar habitat during Christmas, but Knowing X-Boxing day is nearing whilst I respectfully give my support to another’s customary routine, is especially reassuring."
