However, this phrase is grammatically incorrect in Spanish and doesn't make much sense. Here's why:
* "Hermanos" is plural (brothers), but "es" is singular (is). You would need to use the plural form "son" (are).
* "Caliente" can mean "hot" in a literal sense (temperature), but also "sexy" or "attractive." The context is unclear.
Possible meanings depending on context:
* "Hello, my brothers, it's hot!" (If referring to the weather or temperature)
* "Hello, my brothers, it's spicy!" (If referring to food)
* "Hello, my brothers, she's hot!" (If referring to a woman)
It's likely the speaker is trying to express a friendly greeting and perhaps a bit of excitement or humor.
