To tie a brick to the male donkey's genitalia in order to step onto it so that the animal squeezes his rectum around the person's penis. It is a common practice of the Colombian Caribbean Coast and northern regions of Brazil in which male teenagers (sometimes adult men) subjugate donkeys to have sex with them. It is considered a cultural practice in the Colombian Caribbean Coast that determines whether a teenager has become a "real man"; people have attributed it an aphrodisiac connotation assuring that it enlarges the size of the penis. Its name comes from the Spanish "chancletear" (to flip-flop).
