"Mexidodge" refers to an area of town (any town in the U.S.) that has become largely Mexican in appearance and characgter and resembles "dodgy" areas of Mexico. Tiendas, taco shacks, street vendors, tons of kids, etc. etc.
We had been out of Los Angeles for over a decade. Whilst driving East on Santa Monica Blvd. near Western, we couldn't help but notice how "mexidodge" the area had become.
