«¡Eres la leche!» (You’re something else!)

Transcripción de vídeo

Hi! I’m Miguel, a teacher on Real Spanish. I’m sure you have often heard the word «leche» in colloquial conversations. Well it has meany meanings. Some of these expressions are quite vulgar, from “semen” to “to hit onself” (darse una leche), depending on the context. 

But today I’m going to explain the meaning and origin of the phrase «ir (o salir) echando leches», which means “to rush” or “to be in a hurry”. The expression comes from way back, when the milkman or milkmaid delivered milk to people’s homes. They were always in a hurry so that the milk was there for breakfast by the time people got up. The milk often spilled over if the pail was full to overflowing. I mean, the milkman or milkmaid rushed around spilling milk on the ground.

Another expression with the same meaning is «cagando leches». It sounds vulgar, right? Well, when a horse carried the milk churn the milk often spilled over, forming puddles on the ground, as if the horse were shitting.
Milk is very important in Spanish culture. La lechera de Burdos a famous painting by Goya from 1827, was reproduced in this stamp in 1996.

The word leche is used a lot in Spanish, not only to refer to the milk of animals such as cows, goats and sheep, or mother’s milk for babies. The dictionary of the Royal Academy of Spanish (Real Academia Española, RAE) gives nine different meanings for the word. Some of these are very colloquial; for example, una leche may be a slap to the face. There are also many colloquial expressions featuring the word leche. You can see more examples below.

Arroz con leche

Milk and milk products have been part of the gastronomy of Spain for more than 11,000 years. Milk is a component of the Mediterranean diet and is used in many traditional dishes and recipes such as leche merengada, (a dessert prepared with egg yolks, sugar and cinnamon), leche frita (“fried milk”, made with flour, milk and sugar) and arroz con leche (rice pudding).

In some Latin American countries such as Argentina o Nicaragua, tener leche means “to have good luck”. Dulce de leche is a traditional dish made with milk, sugar and vanilla.

The origins of some of these expressions, such as tener mala leche (to be a bad-tempered or unpleasant person), may be related to an old belief that a mother’s milk influenced the baby’s personality. In the past, it was common to hire wet nurses to feed the babies of other women who either could not or didn’t want to breastfeed their own babies. But not just any woman could be accepted as a wet nurse; her original, social status and educational background were very important, as were her physical appearance and her personality. Even Aristotle believed that there was a social connection between people who had been given the same milk, and they should be from the same village or group. Furthermore, Saint Augustine believed that Christian babies should not be fed by non-Christian women, because he believed these children would lose their faith.


Another curious expression is ir cagando leches (or ir echando leches), which means “to go really fast, to do something in a great hurry”. The expression originated from the old practice of delivering milk to people’s homes, early in the morning so they could have breakfast. This was a big rush and the milk used to spill as the lechera (dairy maid) o lechero (milkman) rushed from one house to another.

In the following list we explain some of the most common expressions with the word leche.
