Pinche is one of those words I like to call a "sentence enhacer". It puts extra emphasis on the subject matter at hand.
If you've been studying Spanish for a while, you've likely heard the word pinche. Especially if you've been in any type of social setting where people start letting their hair down. A few chelas bien fría (nice cold beers) and all of sudden the Spanish language starts getting a little more colorful. Although some people don't need beer for that.
So what does "pinche" mean? It's somewhere between damn, god-damn and fucking in English, depending on who you ask. But my understanding is that it's closer to "fucking". Either way, we don't really need an exact translation, what we do need to know is that "pinche" is a pretty strong word, so it's not for polite company.
Let's look at our example sentence:
Sure, calling someone an idiota is a pretty good insulto (insult), but when you throw in our sentence enhancer, pinche, now you're getting serious!
Let's try a few more:
Ese pinche carro es una porquería
That fucking car is a piece of junk
Me cae mal ese pinche cabrón
I don't like that fucking asshole
You can throw in pinche just about anywhere:
Fucking old man
In fact, I actually heard someone use "pinche vieja" in a restaurant one day, it gave me a good chuckle.
Anyway, I hope you enjoyed this pinche entrada (blog post).
Goodbye for now amigos!
