Usage notes
This is a word that frequently draws the ire of people who oppose unofficial synonyms for official words, which they somewhat imprecisely label neologisms. As such, its use often carries an ironic sense (as in the quotations above by Jorge Camacho and Valentin Melnikov), though it is also used simply as a synonym for malbona (as in the other two quotations).
