The name of a game played 24/7/365 by people who know of its existence. The game is played by first saying "Shenanigans", then, the person who said it is allowed to hit or otherwise hurt anyone within earshot of them at the time that they said it. The main target tends to be the groin on males and the chest on females. People who are within earshot when "Shenanigans" is said must say the word "Mulligan" as soon as they hear it to prevent being a target. If someone is hit either before or while you are saying the word "Shenanigans" or after they have said "Mulligan", you are considered to have cheated and they get a free hit on you. Note that saying "Shenanigans" lasts indefinately until each person within earshot has said "Mulligan"
Bob: "SHENANIGANS!" *smacks Tom in the groin*

or

Bob: "SHENANIGANS!"
Tom: "MULLIGAN!"
*Bob hits Tom in the groin*
Tom: oooh, that's a free hit! *smacks Bob in the groin without penalty.*

Usually the result of a bizarre night or encounter that ends in some timeless story.
The other night I bartended at this frat only to wake up the next morning in the attic with three topless girls and no memories... I wonder how I get myself into this type of shenanigans?

A: Dude I know this guy who can get us in to this party at this club in Miami for New Years break.
K: No way! I can only imagine what kind of shenanigans we can get in to.

or the classic...
I have to tell you about my shenanigans the past few weeks

Get the shenaniganeering mug.
Silly or goofy behavior done by a group of friends or closely associated people.

Such silly or goofy behavior is almost always of a good nature, and involves good, sometimes clean fun.

Said behavior will usually happen when all or most people in said group are either bored, hyper, or overly tired.

It can also be identified as the actions done by said group that come about as a result of the friends in such group "getting high off of each other", a phrase used to describe the feeling of being high when around certain friends for a given amount of time, simply because they are awesome and fun to be around and they always have fun together and their company is very much enjoyed.

Shenanigans is also, but less often, referred to as sneaky, deceptive, or mischievious behavior.
1) What happens at CHS when there is a Drama Co. rehearsal AND a Choir rehearsal on the same evening. The break between the two rehearsals often and almost always consists of shenanigans! :)

2)...
*Peter sitting by himself*
*Several friends approach him*
Kim: Hey, man, there's room over there with the rest of us if you wanna join.
Peter: Yes, I'm aware.
Kim: So you wanna sit by yourself like a loner?
Peter: Yeah, I'm fine, thanks.
*Kim and others return*
Leila: What's wrong with Peter?
Kim: Nothing, he just wants to sit by himself, and not join our super-fun shenanigans that we are having.
*All other than Peter (sad face) commence in having a super-fun time of shenanigans*

3) Playing improve games with Nick (happy face). Such games include "freeze", "bang", "atom", "the party game", "psychic battle", etc.

4) Having a dance party outside of the chorus room.

5) Having (and losing) a crab fight with Leila, resulting in accidentally banging your head against a chair.
