Have you ever noticed how dogs act when a piece of meat drops on the floor?
They pounce, they guard it, and they definitely do not share. That exact canine energy is the secret to understanding one of the most useful Mexican slang words you will ever hear on the streets. If you want to sound like a local, you need to know how to call out your friends when they start acting like a hungry golden retriever.
Today we are breaking down aperrarse. The root of the word is "perro" (dog), but the actual meaning is much more specific. It means to get greedy, to hog something, or to bogart a shared resource. But to really get a feel for how it works in the wild, let's look at a classic late-night scenario.
The Taquería Standoff
Picture this. You and your friends are sitting on plastic stools at 2 AM. You just ordered a massive plate of tacos al pastor. The waiter brings exactly one small bowl of the good green salsa and a tiny plate of limes. Your buddy Santi grabs the limes and immediately starts squeezing all of them onto his plate.
Here is how that conversation actually sounds:
Mateo: Pásame los limones, porfa.
Santi: Ya no hay, me los eché todos.
Mateo: ¿Todos? ¿Para tres tacos?
Santi: Es que me gusta la carne con mucho limón.
Mateo: No te aperres, güey, deja algo para los demás.
Santi: Pide más al taquero, no llores.
Mateo: Eres un atascado.
Santi: Bueno, ten mi último limón pues.
Breaking Down the Conversation
Let's look at the mechanics of what Mateo just said and why it works so perfectly.
"No te aperres..."
This is the absolute best way to say "stop hogging it." Mateo is not calling Santi evil or deeply selfish. He is calling him out for a temporary lapse in table manners. The nuance here is crucial. A dictionary might translate greed as "codicia", but nobody uses that word for taco garnishes. You use "aperrarse" for everyday, low-stakes hoarding.
"Me los eché todos"
Santi uses the verb "echar" (to throw) to say "I used them all up." This is standard Mexican casual speech for consuming food or drinks quickly.
"Eres un atascado"
Mateo follows up with another great slang term. An "atascado" is someone who stuffs their face or takes way more than they need. It goes hand-in-hand with our main verb.
How Tone Changes the Meaning
Like most Mexican slang, the music of your voice completely alters the message.
If you say "no te aperres" while laughing and nudging your friend, it translates to a friendly "hey man, pass the guac." It is a lighthearted reminder that we live in a society.
But if you drop your voice, stare them dead in the eyes, and say it flatly? Now you are actually annoyed. You are telling them they are being incredibly selfish and ruining the vibe. Mexican culture places a huge emphasis on sharing food and drinks. Taking the last of a shared plate without asking is a minor social crime, and this verb is the exact weapon you use to police it.
What NOT to Say
When you are trying to tell someone to share, avoid these awkward alternatives.
Awkward Alternative 1: "No te emperres."
This is the ultimate rookie mistake. "Emperrarse" sounds almost identical, and it also comes from the word dog. But it means to get furious, like a barking, rabid dog. If your friend is hogging the salsa and you tell them "no te emperres", they will look at you confused and say they aren't angry at all. (And hey, just so you know, when it comes to food, you'd say "No te aperres" to mean don't be greedy!)
Awkward Alternative 2: "No seas codicioso con la salsa."
"Codicioso" means greedy in a biblical, stealing-gold-coins kind of way. If you use this at a taco stand, you will sound like a dubbed cartoon character from the 1990s.
Generational Secrets
Here is a piece of insider knowledge you will not find in a textbook. If you talk to a Mexican boomer or Gen X speaker, they might use this word entirely differently.
Older generations sometimes use it to mean "working stubbornly hard" or "digging your heels in." They picture a dog biting a bone and refusing to let go. You might hear an older uncle say, "Me aperré en el trabajo para terminar el proyecto." He means he worked like a dog to get it done.
But if you hang out with millennials or Gen Z in Mexico City? The meaning has shifted entirely to hoarding. Young people use it constantly when passing around drinks, sharing a porro at a party, or even when someone refuses to pass the aux cord in the car.
How to Use It in Real Life
You will almost always hear this verb used reflexively (me aperro, te aperras, se aperra). It pops up mostly around shared resources. Think pizza slices, the communal bowl of guacamole, the last cold beer in the cooler, or the microphone at karaoke.
Here are three totally natural ways to drop it into your next conversation:
Spanish: No te aperres con la última rebanada de pizza, déjanos probarla.
Spanish: Se aperró con el micrófono toda la noche, nadie más pudo cantar.
Spanish: Me aperré con el control remoto, no quería perderme mi serie favorita.
So next time you're out with friends and someone starts acting like a greedy pup, you've got the perfect word to call them out! And hey, remember, sharing is caring, especially when it comes to tacos. 😉
