The Local Way to Say It

¡Qué pasa, tronco! Ever had a friend who just can't keep a secret? In Madrid, we've got the perfect word for them: bocazas. It literally means "big mouth," but we use it to describe someone who's a blabbermouth, someone who's loose-lipped and always spills the beans. It's a noun that perfectly captures that annoying trait. When you say someone es un bocazas, you're not just saying they talk a lot; you're saying they talk *too much* and reveal things they shouldn't. It's a common complaint when someone lets slip a surprise or a private detail.

Here are some ways you’d hear it:
  • "No le cuentes el secreto a Ana, ¡es una bocazas!" (Don't tell Ana the secret, she's a blabbermouth!)
  • "Siempre se le escapa todo, ¡qué bocazas!" (Everything always slips out of him, what a bigmouth!)
  • "Mi compañero es un bocazas, ha contado lo de la fiesta sorpresa." (My colleague is a blabbermouth, he's told everyone about the surprise party.)
Grammar

The 'Grammar Math'

Understanding Ser un bocazas is simple once you get the 'Grammar Math' behind it. This is a classic "Ser + noun" construction used to describe an inherent, permanent trait or characteristic of a person. Think of it like this:

Ser + (article) un / una + bocazas = To be a blabbermouth / bigmouth (a permanent trait)

The cool thing about bocazas is that it's gender-neutral in form. The ending 's' doesn't change for masculine or feminine. You just adjust the article:
MasculineFeminine
Él es un bocazasElla es una bocazas

This structure is vital for describing someone's personality. You're not saying they *are being* a blabbermouth right now, but that it's part of who they *are*. It's much stronger and more specific than just saying 'hablar mucho'.
Madrid Life

Madrid Context

Picture this: You're enjoying a caña on a sunny terrace in La Latina, the buzz of the Rastro market still in your ears. Or maybe you're grabbing some tapas with friends in the lively streets of Malasaña. Suddenly, someone reveals a secret about a mutual friend's surprise birthday party. That's the perfect moment to roll your eyes and exclaim, "¡Ay, qué bocazas!" This phrase is perfect for those intimate, real-life conversations among friends – whether you're queuing for a concert at WiZink Center, sharing chismorreos (gossip) on a bench in El Retiro, or complaining about someone on the Metro to Sol. It’s a natural, everyday expression you'll hear and use everywhere in Madrid.
Castilian

The Castilian Tip

A common mistake for learners is to say "hablar mucho" for "blabbermouth." While technically correct for "to talk a lot," it lacks the specific nuance of revealing secrets or being indiscreet. Ser un bocazas is far more precise and carries that direct meaning. Learners often fall into this trap because "hablar mucho" is a more basic, direct translation. In Castilian Spanish, the 'z' in bocazas is pronounced with a clear 'th' sound, like in "thin," which is distinct from many Latin American accents where it might sound more like an 's'. Pay attention to that pronunciation; it's a subtle but important detail that marks you as a true Madrileño speaker!
