When one male poops in the butt hole of another and then proceeds to stick his weiner in the poop covered anus so to make meat and chilli between his buns
When a male and female proceed to have sexual intercourse, and while doing the dirty, the man realizes the girl is on her period, and her blood has rubbed all over his penile unit. In complete disgust, the male vomits all over his own penis, and the puke mixes with the blood, therefore creating a mixture that looks like chili on top of his dog (penis).
