Shenanigans is the universal law of the universe, the law consist of just uttering the word shenanigans and any argument you are in you automatically win no question's asked.
The rule of shenanigans can be summed up as "I Win, You Lose, Fuck You!"
If you are getting robbed and the robber has a gun to your head, and you call shenanigans. The robber is obligated to put the gun down and walk away.

"Why the hell is there a bomb in your luggage?"
