There is such an easy way to sound smart and it involves one simple phrase which is “it ruins the integrity of …”  I know this sounds idiotic but it’s such a broad statement that it’s hard to argue against it.  This statement works great in games especially.  Take beer pong for instance, if someone wants to add a no air ball rule, you just say tell them “no, it ruins the integrity of the game.”  When CK4 tells me a great idea is a bowling ball that knocks down all the pins, the simple response is “that idea is retarded, it ruins the integrity of the game.”  Anytime someone is cheating, you tell them they are ruining the integrity of the game. Look at this definition and tell me you don’t always want to be known as a person with integrity.

in·teg·ri·ty
noun
1. adherence to moral and ethical principles; soundness of moral character; honesty.
2. the state of being whole, entire, or undiminished: to preserve the integrity of the empire.
3. a sound, unimpaired, or perfect condition: the integrity of a ship’s hull.

Plus the best part about this is that people will really like you a lot if you tell them they have a lot of integrity. It has to be one of the ultimate compliments. If you ever find yourself in a room of smart people who you know you can’t compete with, just find a good spot where you can use the word integrity and they’ll respect you for the rest of your life.
