Would it be better if he used just a light trill?
Or just used the usual Texas pronunciation ‘Kahrilllo’?
I'd never have noticed a "Kah-ree-oh" or a "Kah-rill-oh". But the trilling I sure did. As I'm writing in English, I can't even properly write the sound phonetically - it doesn't exist.
It's a pitch to Mexican heritage pimps in an all English commercial. It's offensive to me, just like the Houston radio station "La Raza". They apparently have no idea how disgustingly racist that is, or they don't care.
