Shannanigans are similar to shenanigans, but in the case of shannanigans, they are perpetrated by Shan. It can be assumed that everything Shan does is shannanigans.
"Shan said that the Office is coming back tomorrow, I called shannanigans. I was right."
You declare Shananagans on someone when they have cheaply tricked you in anyway.. whether it buying something, or doing something that you end of feeling scammed. Once declared, you are then allowed to take a broom and beat the crap of whoever you declared it on.
The towns people of South Park declared Shananagans on the carnival folk when they found out the prizes, food, and rides all sucked.. especially the line ride.
law that states, that nonsense actually makes sense,
states that sillyniess is next to happiness sometimes the best time is had when we can just act like little children
also states that 89% of the time ETHAN NELSON is right 100%of the time in 47 states and 2 foreign countries
When you beleive that there is deception or foul play afoot, and you want to be the one that calls it.
You stand up, point at the object/person that you believe to have been involved in the deception and yell "Shannanigans!!" as loud as you can as to attract attention.
However there is an element of risk involved. If you are wrong about the "Shannanigans" call and there is nothing sinister about the situation, you will look like a douchebag
everybody had a hearty chuckle at Jerry when he called Shannanigans on Tom, thinking that he has slept with his wife. Only to find out that he was dead wrong.
A word used by a middle school principle when finding one of his male students making-out with another female student in the backroom of the stage while a play was being performed. It might also derive from a little lepricon who once spoke of great things to myself and many others, yet the true form will never be known.
"Now David, I want no more of these shananagans around my school unless I be apart of it. Shananagans are against our moral code, and will be delt with by thy All Mighty" -Ron Wright
