Technically, “Scullion male goat”. I guess more along the lines of “lowest class of worker, cuckolded guy” as “cabron” seems to be the slang equivalent of the teaGOP “cuck”…
But yeah, people use it for everything. I’ve heard it used when someone was cursing at soap he dropped while grooming a dog “Pinche fucking cabron soap!”. But then, said same guy couldn’t say any sentence without swearing. I really liked him
