Cultural Background

The expression likely comes from wrestling or capoeira, where tripping an opponent is a tactical move. In Brazilian culture, it reflects a historical distrust of bureaucracy and a need to be 'esperto' (smart) to avoid being exploited. It became popular through samba lyrics and soap operas depicting social climbers.

💡

The 'Em' Rule

Always remember to use 'em' after the phrase. You don't just 'passar a perna' someone; you 'passar a perna EM' someone.

⚠️

Not for Pranks

If you just jump-scare a friend, don't use this. It implies a malicious gain or a financial loss.

In 15 Seconds

  • Used when someone cheats or swindles you for personal gain.
  • Literally means 'to pass the leg' or trip someone up.
  • Common in financial, romantic, or professional betrayal contexts.

What It Means

Passar a perna is all about deception and betrayal. Imagine you are walking and someone sticks their leg out. You trip and they move ahead. That is the essence of this idiom. It describes being swindled, cheated, or outsmarted in a dishonest way. It is not just a small joke. It usually involves someone losing money, a job, or trust.

How To Use It

You use it like a regular verb. You can say someone passou a perna in you. Usually, we use the preposition em before the victim. For example: Ele passou a perna em mim. It works for big scams or small office betrayals. You will hear it often in news about corruption or gossip about friends.

When To Use It

Use this when you feel cheated. It is perfect for telling a story about a bad deal. Use it when a salesperson overcharges you. Use it when a colleague takes credit for your work. It adds a bit of drama to your story. It makes you sound like a local who knows the score.

When NOT To Use It

Do not use this for accidental mistakes. If a friend forgets to pay for coffee, that is not passar a perna. That is just a mistake. This phrase requires intent to deceive. Also, avoid it in very high-level legal documents. In a courtroom, use fraude or estelionato. Using this phrase there might sound a bit too colorful.

Cultural Background

Brazilians are generally very wary of the malandro figure. A malandro is a street-smart person who lives by their wits. Sometimes they are charming, but they often passam a perna on others. This phrase reflects a social reality where people have to watch their backs. It is deeply tied to the concept of the jeitinho brasileiro gone wrong.

Common Variations

You might hear dar uma rasteira. This is even more physical. It means to give someone a sweep-kick. Both mean the same thing: to trip someone up. Another variation is ser passado para trás. This means you were left behind because someone cheated you. Stick to passar a perna for the most common impact.

Usage Notes

The phrase is neutral to informal. It is very common in spoken Brazilian Portuguese. Be careful when using it in professional settings as it is a direct accusation of dishonesty.

💡

The 'Em' Rule

Always remember to use 'em' after the phrase. You don't just 'passar a perna' someone; you 'passar a perna EM' someone.

⚠️

Not for Pranks

If you just jump-scare a friend, don't use this. It implies a malicious gain or a financial loss.

💬

The Malandro

In Brazil, being 'malandro' is a double-edged sword. People admire the wit but hate being the one who gets their leg passed!
