GUTS? ¿QUÉ ES?
In general, most Spanish people don't know this word and certainly don't use it in their everyday language. The exact translation for "guts" is "tripas" which is a word that I remember very clearly in Spanish because of the first day when someone offered me the traditional Spanish dish: "callos".
Anyway, the reason that the word "gut" or "guts" is important in English is not because we eat them but because these words are included in a number of different expressions which are quite useful to know. The first is "He has got guts" which means to be brave (valiente). The second is "a gut feeling" which means "corazonada" or "sensación".
Hope that helps!
