À propos of that definition, here's a factoid I learned just yesterday:
In certain Latino dialects, huevos = cojones.
In other words, if you order fried eggs for breakfast in some particular Spanish-speaking country, you'd best know exactly what you're talking about!
Thanks. I'll make sure to cluck like a chicken the next time I place an order of huevos rancheros with a waiter who doesn't speak English.
