A well-established term in the Rio Grande Valley of Texas for any individual whom is a tyrannical short, fat dude married to an ugly woman whose children's names are spelled stupidly and is an utter fool and bi-polar nut case. More commonly used when referring to someone who has inherited a business concern of some sort that he hasn't earned and has no idea how to run, but despite this still manages to find creative ways to embezzle large amounts of money for personal use. A Rodney Mesquias must also come from a family full of individuals devoid of any mental capacity and are abject and well-established losers and who also have no trouble breaking the law both criminally and civilly as a means to an end.
