Every Spanish-speaking country has its own unique slang words.

Learning these informal phrases helps you sound more natural when speaking with locals.

Textbooks usually teach formal Spanish, but native speakers use slang every single day.

I’ll share some of the most common slang words from different Spanish-speaking regions below.

Mexican Spanish slang words

Mexico has a very rich and colorful vocabulary for everyday conversations.

You’ll hear these words everywhere from the streets of Mexico City to popular television shows.

Güey

This is probably the most famous Mexican slang word.

It translates roughly to “dude” or “bro” in English.

Mexicans use it constantly with friends to grab their attention or emphasize a point.

Chido

When something is good, nice, or cool, Mexicans call it chido.

It’s a very positive word used to describe objects, situations, or even people.

No manches

This phrase translates literally to “don’t stain” but it actually means “no way” or “you’re kidding”.

You use it when you’re surprised by something someone just told you.

Colombian Spanish slang words

Colombian Spanish is known for being very clear, but it still has plenty of local slang.

These words are especially common in cities like Medellín and Bogotá.

Parce

This is the Colombian equivalent of “dude” or “bro”.

It’s short for parcero and is used to refer to a good friend.

Chévere

Chévere is a very popular word used to describe something awesome or fantastic.

While it’s used in other countries like Venezuela, it’s a staple of Colombian conversations.

Bacano

This is another word that means “cool” or “great”.

If someone tells you a good story, you can respond by saying that it’s bacano.

Argentine Spanish slang words

Argentina has a very distinct accent and a unique slang dictionary known as Lunfardo.

You’ll notice these words immediately if you visit Buenos Aires.

Che

This is the ultimate Argentine filler word.

It means “hey” or “mate” and is used to get someone’s attention before speaking.

Boludo

This word can be an insult meaning “idiot”, but friends use it affectionately to mean “dude”.

You’ll often hear it paired with che in everyday greetings.

Copado

When an Argentine thinks something is cool or someone is a great person, they use copado.

It’s a great way to show enthusiasm.

Spanish slang words from Spain

The Spanish spoken in Spain sounds quite different from Latin American Spanish.

Their slang is very unique to the Iberian Peninsula.

Tío / Tía

Literally, these words mean “uncle” and “aunt”.

However, young people in Spain use them constantly to mean “guy” or “girl” or “dude”.

Molar

This is a verb that means “to be cool” or “to like”.

Instead of saying me gusta (I like it), people in Spain often say me mola.

Guay

This is the classic word from Spain for “cool” or “great”.

If someone asks how your weekend was, you can simply reply with guay.
