Dressing up with our Taco Bell “Diablo” Hot Sauce Costume will certify you as the hottest persona nongrata at the party. Diablo is a Spanish word meaning “Devil”. Diablo Sauce is a grade of hot sauce given out for free at Taco Bell. It is the spiciest, zestiest, scovill-iest hot sauce the food-conglomerate has to offer. A definite hit at any Halloween party, you can spend the whole night asking strangers if they’ve “ever tried Diablo?” And if they “want to?”. Availability: This Hot Sauce Costume takes approximately 1 business day to leave the warehouse plus transit time.
