Xavistick 

The behavior of a person who is a narcissistic pendeho, i.e. displays xavinism in always having a better idea and unapologetic for usually being wrong.

Xavistick behavior: A guest insisted on grilling the steaks and ignored others who who alerted him to the flaming grill. He served burned meat-chips and efused about how great they tasted.

Xavististick: cha-vist'-ik to behave as knowing better than others, treating others as inferior, narcissistic. Unapologetic when shown to be wrong. Nit-picky and irritating.

"Would you please stop being xavistick!", said the host to a guest who criticized another for the way they poured water into a glass.
