mau negócio

You’ll mostly see this phrase paired with three main verbs: ser (to be), fazer (to make/do), and parecer (to seem). If you’re looking at a used car that has more rust than paint, you’d say, Isso parece um mau negócio. If you actually bought it, you’d sadly admit, Eu fiz um mau negócio. Notice that the adjective mau comes *before* the noun negócio. In Portuguese, adjectives usually follow nouns, but for certain fixed expressions like this one, flipping them makes it sound much more natural. It’s like the difference between saying 'a bad deal' and 'a deal that is bad'—one just clicks better. Also, remember that mau is the opposite of bom. So, if you win the lottery, you made a bom negócio (well, technically that's just luck, but you get the point).

Imagine you’re scrolling through a food delivery app at 2 AM. You see a burger that costs $30 but the reviews say it tastes like wet socks. You think to yourself, Pedir esse lanche é um mau negócio. Or maybe you're a travel vlogger and you find a 'luxury' hotel that doesn't have electricity. You’d tell your followers, Gente, ficar aqui é um mau negócio. In a more professional setting, like a Zoom interview, if a company offers you a high salary but expects you to work 100 hours a week with no holidays, you might tell a confidant, Essa proposta parece um mau negócio. It works perfectly for those 'too good to be true' TikTok trends too—like those 'get rich quick' schemes that only result in you losing your initial $50.

Use this phrase whenever there is an exchange involved. It could be exchanging money for a product, time for a job, or even your peace of mind for a relationship. It’s perfect for online shopping regrets, especially when that 'vintage' jacket from an obscure website turns out to be a toddler's size. It’s also great for social advice. If your friend wants to trade their PS5 for a bag of magic beans, you must intervene with, Isso é um mau negócio, cara!. It's professional enough for a boardroom but casual enough for a WhatsApp group chat. Basically, if there's a 'cost' and the 'benefit' is missing, mau negócio is your weapon of choice.

Don't use mau negócio for things that aren't 'deals' or transactions. If the weather is bad, you don't have a mau negócio of a day; you just have tempo mau (or tempo ruim). If your coffee tastes bitter because you forgot the sugar, that’s not a mau negócio, that’s just a café ruim. Also, avoid using it for serious moral failings. If someone is a 'bad person', they aren't a mau negócio (unless you're dating them, then maybe the relationship is!). It requires a sense of exchange. Don't use it to describe a movie you didn't like unless you're specifically complaining that the ticket price wasn't worth the two hours of boredom.

A huge trap for learners is the mau vs. mal distinction. Mau is an adjective (the opposite of bom), while mal is an adverb (the opposite of bem). Since a 'deal' is a noun, you must use the adjective. Saying ✗ mal negócio is like saying 'badly business'—it sounds a bit clunky and will give away your 'gringo' status immediately. Another mistake is the word order. While negócio mau is grammatically possible, it sounds like you’re describing a 'business that has an evil personality'. Stick to mau negócio to keep the 'bad deal' meaning intact.

• ✗ Esse é um mal negócio. → ✓ Esse é um mau negócio.
• ✗ Fiz um negócio mau. → ✓ Fiz um mau negócio.

If you want to sound like a true local, you can use furada or roubada. Furada literally means 'a hole', but in slang, it means a trap or a situation that's going to end badly. If a friend invites you to a party that turns out to be a pyramid scheme presentation, that’s a furada. Roubada (literally 'a robbery') is similar—it’s a situation where you feel cheated or like you're wasting your time. For a more formal vibe, you could say investimento ruim (bad investment) or proposta desvantajosa (disadvantageous proposal). But honestly, mau negócio is the 'Little Black Dress' of Portuguese—it fits almost everywhere.

You can spice this up by adding intensifiers. If the deal is truly catastrophic, call it a péssimo negócio (terrible business). If you want to be a bit more dramatic on social media, you can say o pior negócio da minha vida (the worst deal of my life). In Portugal, you might hear grande mau negócio to emphasize the scale of the failure. You can also turn it around: Não é um mau negócio (It’s not a bad deal) is a classic way of saying 'it's actually pretty decent' without sounding too enthusiastic. We wouldn't want to look too excited and lose our bargaining power, right?

Is it formal or informal? It's neutral! You can use it with your boss or your best friend. Does it only apply to money? No, it can apply to time, effort, or relationships. Is there a plural? Yes: maus negócios. For example, Ele sempre faz maus negócios (He always makes bad deals). Can I use it for people? Only if you're talking about the 'deal' of interacting with them (e.g., 'Hiring him was a mau negócio'). Just be careful not to hurt anyone's feelings—unless they really did sell you a fake iPhone.
