Not Opposite Day

See opposite day.

1. A term used to describe that it is, in fact, opposite day which can only be used on opposite day. The

"not" is usually over-emphasized, and the term usually follows a wink, nudge or other non-verbal que that the speaker means the opposite.
The rational behind this use of the term is that if it is Opposite Day, then the correct way of proclaiming that it's Opposite Day, is by actually proclaiming how it isn't Opposite Day.
This is the most commonly used form of the phrase.

2. A term that is used to genuinely describe how it is not opposite day. This use of the phrase is usually used by those that do not plan on partaking in Opposite Day, and therefor will mention that it's actually "not Opposite Day" when people say it is (or on Opposite Day, isn't). This usually does not work, as the pro-Opposite Day party acts as if the other party is in cahoots with them, not shutting them down.
1. "Guess what today ISN'T. Today is NOT Opposite Day!" *wink* *nudge*

2. "Stop saying that it's opposite day, because it's not Opposite Day." ... "That's not what I meant, I'm not agreeing with you in Opposite language, I'm trying to tell you that it isn't opposite day!" ... "UGH!"

Opposite Day

Opposite Day (n): Today is opposite day, so you must say no for yes and yes for no. It's also the only day you go back and stay back.

Opposite Day is the day where everything is reversed. But if opposite day is opposite day then shouldn't opposite day be opposite to opposite day? Meaning that everything that is opposite is opposite because opposite is opposite of opposite
2nd Grader: Hey student(teacher in this case), did you know today is opposite day.
Teacher: No, I didn't. But if today is opposite day little Timmy, shouldn't it be opposite?
2nd Grader: Wtf does that say?

Opposite day

Celebrated on April 30th, the opposite of April 1st. The day when you are nice to your boss, teacher, enemy and can be a complete Ahole to your best friends. You can just say the opposite of what you want to say, and confuse/laugh at all the people who dont know why you are saying what you are saying.

Because April fools, has become a cliche.

Also spelled yad etisoppO, and occipatai
