🌍

Contexto cultural

In Brazil, this phrase is a staple of 'futebol' culture. It is used by fans and players alike to demand more effort. It's linked to the concept of 'raça' (spirit/grit). In Portugal, the phrase is understood but can sound a bit more 'dramatic' or 'old-fashioned' compared to its daily use in Brazil. It's often reserved for truly epic struggles. In Angolan Portuguese, while the phrase is known, you might also hear metaphors involving the strength of the lion or the resilience of the land to express similar determination. In the 'Faria Lima' (financial district) culture of São Paulo, this phrase is used to describe a 'shark' mentality in business deals.

Use for motivation

It's a great phrase to use when you want to pump up your friends before a challenge.

⚠️

Don't be too literal

Never use this if you are actually angry at someone in a dangerous way; it might be taken as a threat.
