Why Learn Spanish Slang?
Spanish slang is the difference between understanding words and understanding people. While textbook Spanish gets you basic communication, slang helps you understand the jokes, cultural references, and casual banter of the locals. Having a clear understanding of these will also help you gain confidence in using them in actual conversations to build rapport and show your familiarity with the language and the locals.
Whether you’re watching a Spanish TV show, listening to music, or talking on the street, slang appears everywhere. Recognizing common phrases lets you follow dialogues, understand jokes, and avoid misunderstandings in real life. In short, mastering Spanish slang transforms basic language skills into genuine connections with native speakers.
Spanish Slang Words And Phrases
Whether you're looking for useful and interesting Spanish slang phrases from Spain, Mexico, or other Spanish-speaking countries, we've got you.
European Spanish Slang
Tío/tía ¿qué pasa?
Tío and tía are Spanish slang for "dude" and "girl", while ¿qué pasa? is an informal way to ask "what's up?", so the phrase is "dude, what's up? Use this greeting with friends in a casual setting.
Note that tío and tía actually mean "uncle" and "aunt" in Spanish, but in Spain, they are more often used as a colloquial way to say "guy", "dude", "girl", "chick" and so on.
¿Cómo te va?
This is another way to ask "what's up?" or "how's it going?" colloquially.
Estar como una cabra
This Spanish slang expression literally means "to be like a goat", but it is used colloquially to mean "to be crazy". It is similar to the English expression "to be nuts".

Pijo/a
This slang word is used to describe people as snobby, stuck up, or spoiled.
See una fresa in "Mexican Slang Words" for the equivalent Mexican slang term.
Ir a su bola
When someone is minding their own business or doing their own thing, you can say él va a su bola, or "he's doing his thing".
Es una mierda
You cannot learn Spanish slang without learning at least one curse word! Mierda means sh*t, and this saying can be translated as "it's a piece of sh*t", "it's crap" or "it sucks".
A native Spanish speaker might use es una mierda to refer to a situation that is rubbish or an item or food that is of low quality. La comida es una mierda is "food is bad quality/ crap".
¡Qué mala pata!
If something unfortunate happens, you can say "what a bad paw", meaning "what bad luck". This comes from the Spanish superstition that carrying a rabbit's leg, or pata, brings good luck.
Ser la leche
If something es la leche, it is "cool" or "great". This phrase can also be used to say él piensa que es la leche, "he thinks he's all that", which in this context would be a negative attribute.
Me cago en la leche
Unlike ser la leche, when native speakers say "I sh*t in the milk", this is definitely not a good thing! This unusual phrase means "f*cking sh*t", "bloody hell" or "motherf*cker". It is used to express extreme disappointment or shock at a negative situation.
La mala leche
This phrase literally translates as "to have bad milk", but figuratively, it is used in Spain and different Latin American countries to mean various things, depending on where you are and how you use it.
In Spain, if you say tener mala leche, it means that someone acts in bad faith, while if you say estar de mala leche, this means that a person is in a bad mood.
See la mala leche in "Other Latin American Slang" for different definitions.
Mexican Slang Words
Mexico is the largest Spanish-speaking country in the world, so it is only fair to dedicate a section to slang specific to this culture-rich country.
Mexican Spanish has distinct accents, dialects, and commonly used phrases. Let's have a look at some of the most useful Mexican Spanish sayings.
Oye güey
This Mexican Spanish slang greeting means "hey dude". Güey, meaning "buddy", "mate" etc., is often used as a filler word in conversations in Mexico.
¡No manches!/ ¡No mames!
To express shock or disbelief, you can use either of these colloquial expressions the same way. They can both be positive or negative depending on the context and tone of voice.
The literal translation of no manches is "do not stain", however, it is used as "no way" or "holy cow" in colloquial Mexican.
No mames is a little cruder, as it literally means "do not suck". You will hear güey, no mames in Mexico when someone wants to say "dude, don't mess with me".
¡Chale!
This is an interjection used in Mexico to express surprise and disappointment. It is rather like the English sayings "give me a break!" or "you're kidding!"
Pendejo
If you watch a lot of Mexican TV, you might have heard someone be referred to as a pendejo. This is a useful Mexican slang term that literally means "pubic hair" but is used commonly in Mexico to mean "dickhead".
Una fresa
Referring to someone as "a strawberry" in Mexico implies that they are snobby, pretentious, and privileged. Nonetheless, this kind of person is looked up to by poorer Mexican young people.

La neta
This slang word means "truth". Saying la neta is like asking "really?" or emphasizing something. La neta te amo is "the truth is I love you".
¡Qué padre!
There are a few ways to express delight about a situation switch your Mexican friends, and this is one of them. This Mexican Spanish slang phrase means "how cool!", "that's great!" or "nice!" Its literal translation is "what father", but obviously this is not how it is used.
¡Qué onda!
This phrase means "what a wave" when translated literally, but in Mexico, it is a very common way to greet someone and it is used as "what's up?" This phrase might have a Mexican origin, but you can also use ¡qué onda! in Argentina and Chile.
Buena onda/ Mala onda
In Mexican slang, onda, which means "wave" is also used to describe someone's personality. If someone is buena onda, they are cool or nice, and on the flip side, if ella es mala onda, "she is not cool".
Spanish speakers from other Spanish-speaking countries will understand if you use onda in this way, but it is not common outside of Mexico.
¡Qué buena onda!/ ¡Qué mala onda!: Mexicans also use "what a good wave/ what a bad wave" to express their feelings about a situation. While qué buena onda is used to express "how cool!" or "so cool!", qué mala onda means "too bad", "how bad" or "uncool".
Other Latin American Slang
Across other Latin American countries, there is a range of extremely helpful slang. We will briefly touch on some notable examples.
Mae, pura vida
This is slang from Costa Rica that means "mate, how's it going?". You can reply with pura vida to mean "it's going good".
Pura vida is a super general term that can also be used to express thanks, good vibes, and any other positive greeting or farewell. This saying is very specific to Costa Rica and it can be used all over the country.
Estar asado
In Peru, you can express your anger by saying you are "roasted". No me hables, estoy asado means "don't talk to me, I'm angry." In other dialects across Latin America, you can say estoy enojado/a, while in Spain, you would say estoy enfadado/a.
Estar prendido
Prendido is a super useful slang word. This phrase means "to be lit" or "to be buzzed". Used in Colombia, Panamá, the Dominican Republic, and Venezuela, you can say estoy prendido/a if you are drunk, but in a positive way. It implies you are full of energy and good vibes.
La mala leche
We have seen that in Spain, this saying is used to describe someone with a bad temper or attitude. However, in Venezuela and Panamá, it is used to express mala suerte, or bad luck.
In Chile and Argentina, if someone has la mala leche, they have acted maliciously toward another person.
