Man of Many Names
If you look up Pablo Escobar in say Wikipedia, they will have a long list of nicknames and aliases that Pablo went by. Some of the more popular are “El Patron” and “Don Pablo” which obviously have ties to being the bossman in one way or another. You might recognize “Don” from the Godfather movies where the Don was the head of the family. That same loyalty and respect was commanded by Pablo and over time the name was a perfect fit.
