Translation:The fisherman drinks a cup of coffee.
I've seen it explained on other posts. Xicara is a cup, like a tea cup, also used as a measurement in recipes. It is often decorative, made of fine ceramic. Copo is a glass, like a glass of water in restaurants, usually made of glass or clear plastic. There is another word that is used for mugs, like a coffee mug, made out of stonewear.
