Literally, 'tener mala leche' translates to 'to have bad milk'.
In reality, it means someone is in a bad mood or has a bad temper.
No le hables al jefe hoy, que se levantó con mala leche.
B2Don't talk to the boss today, he woke up in a bad mood.
El comentario que hizo no fue una broma, lo dijo con muy mala leche.

B2My neighbor is a very ill-tempered man, he's always complaining about everything.
This phrase has a fascinating origin! It's believed to come from the ancient belief that a wet nurse's milk could pass on her personal qualities to the baby. If the nurse was bad-tempered or unhealthy, her 'bad milk' (mala leche) was thought to make the child grow up to be grumpy and unpleasant. So, someone with 'mala leche' was cursed from the start!
This is a versatile idiom! You can use it in three main ways: 1. To describe a temporary mood: 'Estoy de mala leche' (I'm in a bad mood). 2. To describe someone's general personality: 'Ese hombre tiene mala leche' (That man is ill-tempered). 3. To describe an action done with malice: 'Me lo dijo con mala leche' (He told me that with bad intentions).
Mistake: “Using this phrase when talking about milk that has gone bad.”
Correction: This expression is almost never used literally. If you want to say milk has spoiled, you would say 'la leche está mala' or 'la leche se ha cortado'. 'Tener mala leche' is all about people's tempers and intentions.

Great question! It's like the difference between 'being' and 'acting'. 'Tener mala leche' often describes a person's permanent character trait (He *is* a grumpy person). 'Estar de mala leche' describes a temporary state (He *is in* a bad mood right now). If someone is usually nice but is grumpy today, you'd use 'está de mala leche'.
It's very informal and direct, so you wouldn't say it to your boss. Among friends, it's perfectly normal. Calling someone 'un mala leche' (a mean-spirited person) is a strong insult, but saying someone 'tiene mala leche' today is just a common observation.
