Relatively common in Spanish slang (and particularly the Spanish of the southern cone South America) is the set of words requete and the prefix re-. These all serve to emphasize the next word in the sentence.

So, "re-caliente" would mean really hot, like it is in Mendoza right now. You could also say that "el tiempo es re-feo" or "requete-feo" meaning really ugly weather.

Re is also a homograph for "rey" or king - hence my feeling that this is the "king" of superlatives. I'm hilarious, I know.
