It is when a man covers his dick in cinnamon sugar and proceeds in anal intercourse. During the course of fucking, the person receiving the anal will most likely shit all over the man's dick. Rather then wiping the shit off, the man will keep it there until he cums in the other person's ass. As the man pulls out, his dick will resemble that of a churro. Meaning, a stick covered in cinnamon sugar, fudge and whipped cream. Or in other words, a dick covered in shit and his own semen.
For extra fun, the man may ask the one who took the anal if he or she is hungry. Most likely after enduring the anal, the person will say yes. Which then the man will proceed to throat fuck them with his churro. Satisfying their hunger.

Ryan: "AWWWW. Sick nasty."
Anthony: "Yeah, what a slut."
