El Wong refers to a spanish-speaking person bearing "Wong" as part of their name. This combination completely disrupts any other name the recipient had and makes them only be able to be called "El Wong" from the moment they are on a spanish-speaking country.
For added effect, one might call them "El pinchi Wong"
This alias also makes the person 80% cooler
