My wife has 3 pet names for me: “Güero, “Amor,” and “PENDEJO.”
I’d say the last one is her favorite, given how often she uses it, heh.
If you don’t speak Mexican Spanish, you may not get the joke. “Pendejo” has quite a few meanings, but the most common in Mexico is “dumb-ass,” only slightly stronger and with interesting nuances.
Want to know its origin? Okay!
It comes from the Latin “pectiniculus” (diminutive of “pecten”).
