Cuñadismo 

Spanish slang that literally translates to "Brother-in-law-ism". Refers to an attitude of excessive nihilism, know-it-all or conservatism often justified with fallacy and post-truth statements. The main difference between a cuñado and an average moronic blabbermouth is that the cuñado treats everybody with familiarity, has a high opinion of himself and (in fact) might be more successful than you in everything.

Also, for some Left-wing supporters in Spain, referred to the line of thought of right-center/liberal political parties such as C's or UPyD.

In other words, cuñadismo comprises all the reasons why you hate your brother/sister-in-law so much.
(See meninism for a somehow simil in Anglo-saxon culture)

chadismo 

When a con artist thinks he’s a fine artist... his verbose pathology gives it away.

After hearing his 427 & 1/2 years experience in 7 trades at 38, I realized the chadismo was strong with this one.
