Rematar. (verb) - To close out, to wrap up, to finish off.

Popped in to my favorite tapas bar to grab a quick snack before heading to the library. Greeted the bartender with an, "Hola, Que tal?"

He replied, "Rematando la manana."

"Ohhh...siii," I responded. Then thought to myself, confusedly, 'But. But. It's 3:30 pm!"
