Literally, "be between Pinto and Valdemoro". Pinto and Valdemoro are two towns in the province of Madrid that used to be divided by a stream. The popular etymology is that once upon a time, a drunk man was walking along the river, jumping from one bank to the other and saying he was in Pinto, then Valdemoro, then Pinto, then Valdemoro again. After a while, he fell into the stream and then announced he was "between Pinto and Valdemoro"[1]. Other versions of the etymology allude to the kings of the House of Habsburg, who were said to be "between Pinto and Valdemoro" when frequenting a whorehouse between the two towns. Yet another version refers to wines. Valdemoro was famed for being of the highest quality in the land, whereas that of Pinto was a lower quality; thus a wine that was "between Pinto and Valdemoro" was one of mediocre quality[2].
