Y2K stands for "Yet, 2sdays Kill" and was a catastrophic calamity that occurred in 2000. In the late 20th Century, only the last two digits of years were stored in computers. For some reason, this failed to prevent Tuesdays (abbreviated "2sdays") from killing random and innocent civilians. No one anticipated this and so they were totally unprepared for what was to come. Except for those who went out and stocked up on bottled water in preparation. Those people were prepared.

The good side of Y2K: It gave Peter Gibbons a reason to be hired by Initech and all Office Space fans are very happy about that. It also gave the media something to bitch about on slow news days.

Y2K is not to be confused with MBA. No one ever does because they have nothing to do with each other.


One of the most ridiculous words in the English language. Though spelled as though it should rhyme with 'thatched' it's actually pronounced 'concertina'. It refers to the soft underbelly of a household cat. If you want to know about yachts, hang out in doctor's waiting rooms. Copies of Which Fucking Yacht, Which PDA and Which Small Caribbean Country are always available to make you feel small.

Alphabetical Order[edit]

The arrangement of words, phrases, names, and anything else made up of the twenty-nine characters (letters) in the English alphabet, in a precise order. The order was created by kindergarteners who decided to write a song arranging these letters in a specific order (the phrase "Now I know my ABC's. Next time won't you sing with me?" was later added by kindergarten teachers who thought their students weren't smart enough to memorize the song without that playful ending). That order is decided by taking the first letter in every word and arranging them in the order they are arranged in in the song. If these letters happen to be the same, then you proceed to the second letter, etc. For some reason, blank spaces come before "A," and punctuation and numbers are allowed into the order. All words in the English language can be found in perfect alphabetical order in a common dictionary.

Yes does not automatically necessarily mean not-no, as in the affirmative response. Try asking your girlfriend if she's okay after she's been sulking for an hour. Believe me, she'll say yes but she sure as shit won't mean it. In this particular case, it means, 'Oh fuck off, you selfish bastard.' Or, when used with yes means no and no means yes, can be made to mean whatever the hell the torturer feels like. Now try asking if she wants it up the arse. No means no now, don't it? Do it anyway because how else is she going to learn?)

Youghurt is milk inside some jam, and tastes terrible. There are several types of youghurt, like:
