* Courage: "He has the cojones to stand up to the bully."
* Bravado: "He showed off his cojones by jumping off the cliff."
* Audacity: "It took a lot of cojones to ask her out on a date."
It's important to note: Using "cojones" is considered very offensive in formal settings or when speaking to someone you don't know well.
If you're looking for a more polite way to express courage or boldness, you could use phrases like:
* Tener valor: To have courage
* Ser valiente: To be brave
* Tener agallas: To have guts
* Tener determinación: To have determination
Remember, using slang terms like "cojones" can be very inappropriate in certain situations. Always consider your audience and the context when choosing your words.
