(also known as: appeal to the common man)
Description: In place of evidence, attempting to establish a connection to the audience based on being a “regular person” just like each of them. Then suggesting that your proposition is something that all common folk believe or should accept.
X is just common folk wisdom.

Person 1 is a common man who proposes Y.
You are also a common man.
Therefore, you should accept Y.
My fellow Americans, I am just like you. Sure, I have a few private jets and a home in twelve countries, but I put on my pants one leg at a time, just like you common people. So believe me when I say, this increase in taxes for the common folk is just what we all need.
Explanation: There is no valid reason given for the increase in taxes.
You don't want a hot dog and beer? Eating hot dogs and drinking beer at a baseball game is the American thing to do.
Explanation: Here the person making the argument is appealing to the tradition of the common folk.
Exception: If the “common folk” appeal is made in addition to valid reasons, then it is not a fallacy, although I would argue it is cheap pandering that many people can easily detect.
