Basically, being proud is a virtue. Any word that puts being proud in a negative light is a lie in the word itself. Need to erase these words from the language.
Pretending to be proud about an unworthy thing or a thing you stole is a lie. Any additional synonyms are an unnecessary complication. Any unnecessary complication is a work of a devil, in these times usually under a skin of the Matrix.
So if you want to say that Trump is a lier, say it. Because there is no such thing as narcissist.
