A razzmatazz is a ploy to attract attention, it is usually loud or exuberant. It is thought to come from razzle-dazzle, and carries the connotation that the action is done to deceive or distract someone. It has no plural.
Razzamatazz is a variant spelling of razzmatazz, and it is extremely less common. Some list it as the British spelling, however, it is found both inside and outside the Unites States. However, in Spanish the word stays as razzmatazz.
