Comer Caña
To have sex. The term refers to the squelching or slapping sounds made during intercourse, which are compared to the wet noise of someone chewing on the fibrous stalk of a sugarcane (a staple crop and snack in the Dominican Republic).
Manuel: Where is Luis? Esteban: He is at a love motel with his girl, comiendo caña like crazy...
